AHLERS, Judge.

At the time they divorced in 2011, Rachel1 and Brett Diercks had two sons,

born in 2007 and 2008. In their dissolution of marriage decree, they were granted

joint legal custody and joint physical care2 of the children. At the time, the father

lived in Bettendorf and the mother began residing in Illinois, less than one hour

from Bettendorf.

After the divorce, the mother moved to a different town in Illinois farther from

Bettendorf, and the boys began residing primarily with the father. The mother’s

move prompted a 2015 modification to the divorce decree. The stipulated

modification decree changed the mother’s parenting time. The modified decree

provided for the mother to have time with the children every other weekend, on a

designated holiday/break schedule, and for two periods of three weeks each during

the summer.

After a brief move to Wisconsin, the mother, her new husband, and their

children moved to Florida in 2019.3 They also maintain a summer home in northern

Wisconsin. Despite the move reducing her opportunities for time with the children,

the mother returned regularly to Iowa to exercise parenting time with the children.

In 2020, the mother filed this action seeking modification of her parenting schedule.

1 Rachel remarried after the parties divorced and is now known as Rachel Ullrich.
2 The dissolution of marriage decree refers to the physical-care arrangement as
“shared physical care,” but we interpret it to mean “joint physical care,” the
terminology used in the Iowa Code for a shared parenting time arrangement under
which neither parent has physical care rights superior to those of the other parent.
See Iowa Code § 598.1(4) (2011) (defining “joint physical care”).
3 The mother and her new husband have two children together, and he has two

children from a prior relationship. The two children at issue in this matter remain
in Bettendorf with the father.
 3

Following a trial, a ruling, and a ruling on post-ruling motions, the district court

modified the mother’s parenting time by reducing her weekend time to one

weekend per month, leaving the holiday/break schedule largely intact, and

increasing the mother’s summer parenting time. The new summer schedule gave

the mother a continuous period of time with the children starting one week after

the children’s school year concludes and ending two weeks before the next school

year begins. The court also required use of a jointly-accessible Google calendar

to help the parties communicate about the children’s activities. The father appeals.

I. Issues Presented

The father raises four arguments: (1) the court erred by increasing the

length of the mother’s summer parenting time with the children; (2) the court erred

by not requiring the mother to take the children to their activities during her time

with the children; (3) the court erred by requiring the use of a Google calendar

without providing sufficient guidance as to its use or impact on the parties; and

(4) the court erred by precluding the father from calling multiple witnesses. We will

address the challenges on the merits before addressing the challenge regarding

exclusion of witnesses.

II. Change in the Parenting Schedule

A. Scope and Standard of Review

This is an action to modify a dissolution decree, so our review is de novo. 4

With de novo review, we give weight to the district court’s fact findings, particularly

concerning the credibility of witnesses, but we are not bound by them.5 Typically,

4 See In re Marriage of Sisson, 843 N.W.2d 866, 870 (Iowa 2014).
5 Sisson, 843 N.W.2d at 870.

we refer to the schedule the parents have with the children in a joint-physical-care

arrangement as a parenting schedule, a parenting plan, or parenting time. In

contrast, when one parent has physical care, we commonly refer to the other

parent’s schedule of time with the children as visitation or a visitation schedule.

Here, despite the children residing primarily with the father, the parents continue

to be classified as having joint physical care of the children, and neither party

challenges that classification. Even though that remains the classification, both

parties and the district court regularly refer to the mother’s time with the children

as visitation—a term that seems to be inconsistent with a joint-physical-care

arrangement. In the end, any terminology inconsistency is inconsequential, as the

standards that apply to modifying a parenting schedule in a joint-physical-care

arrangement are the same that apply to modifying a visitation schedule in an

arrangement in which the other parent has physical care.6 The standard is that

the parent seeking the modification must establish that there has been a material

change in circumstances since the latest decree and that the requested change in

the parenting schedule is in the best interests of the children.7

B. Analysis

At the heart of this dispute is the geographic distance between each

parent’s home and the impact the children’s extracurricular activities have on the

parenting schedule. The children, in sixth and eighth grade at the time of trial, are

extraordinarily involved in their activities. While both children wrestle, wrestling is

(applying the lower burden for modifying visitation to an action seeking to modify
the parenting schedule for parents with joint physical care).

the older child’s passion. He participates in various styles of wrestling nearly year-

round and is nationally ranked. As he approaches high school age, he is a varsity

hopeful. Testimony was presented regarding the positive impact participation has

had on him in gaining self-confidence, accountability, and an impressive work

ethic. The younger child has also seen success in wrestling and is a champion

go-kart racer. His activities also keep him solidly booked throughout the year.

Both parties testified to the requirements the father imposes when the

mother comes to Iowa to visit the children. He attempts to control the scheduling

of their homework, eating, sleeping, and extracurricular activities. The district court

characterized these requirements as restrictions on the mother’s parenting time.

1. The Mother’s Summer Parenting Time

The parties agree that the mother’s move to Florida is a material change in

circumstances that would permit modification of the parenting schedule. As there

is a material change in circumstance, the only remaining issue is whether the

change in the mother’s parenting time schedule is in the children’s best interest.8

Due to the fact-intensive nature of making decisions involving the children’s best

interests, prior cases are of little precedential value.9

To resolve this issue, we begin with the small picture and note that the

change in the parenting schedule is not significant. Before this modification action,

the mother received six weeks of parenting time in the summer. The district court’s

8 See Brown, 778 N.W.2d at 51–53 (holding that a parent seeking to modify a
parenting schedule needs to show a material change in circumstances and that
the requested change is in the children’s best interests).
9 In re Marriage of Weidner, 338 N.W.2d 351, 356 (Iowa 1983) (“Prior cases have

little precedential value; we must base our decision primarily on the particular
circumstances of the parties in this case.”).
 6

order modified the summer schedule to give the mother the period starting seven

days after the last day of school in the spring and ending fourteen days before

school resumes in the late summer. Depending on the schedule set by the

children’s school district, including the variable number of snow days that can

extend the school year in the spring, this may result in little to no additional summer

time for the mother. At most, it adds approximately two weeks to the mother’s

summer parenting time. We do not view this as the drastic change the father

claims it to be, especially when we consider that the mother’s time during the

school year is reduced from every other weekend to one weekend per month. It

is quite possible that after the modification the mother will end up with less

parenting time than she had before. Even if there is a slight increase in parenting

time, the tradeoff between less time during the school year and more time in the

summer is a reasonable one given the distance between the parents’ homes.

We turn next to the bigger picture, which involves addressing the tension

between the mother’s parenting time and the children’s extracurricular activities.

This involves weighing competing interests. On the one hand, the children and

mother have a right to spend time with each other. Continuing and frequent contact

with both parents is generally in the children’s best interests, especially when, as

here, there is a good relationship between the mother and the children.10 Iowa

Code section 598.41(1)(a) (2020) declares a policy that, in setting the parenting

arrangements, courts are to “assure the child[ren] the opportunity for the maximum

continuing physical and emotional contact with both parents . . . and which will

10See In re Marriage of Greenspon, No. 19-1382, 2020 WL 5650479, at *3 (Iowa
Ct. App. Sept. 23, 2020).
 7

encourage parents to share the rights and responsibilities of raising the child[ren]

unless direct physical harm or significant emotional harm” is likely to result. There

is no claim—and no evidence to support a claim—that the mother poses a risk to

the children’s welfare. The benefits to the children in having as much time as

possible with their mother—as is reasonable under the circumstances—are a

heavy consideration.

On the other hand, “the best-interests equation factors in more than just

parental contact. It takes into account the experiences that children need to

promote their own growth and development, independent of their parents.”11 Our

court has recognized that a child approaching middle school years “will presumably

be increasingly involved with school and friendship related activities.” 12 The

children’s extracurricular activities take time that potentially interferes with the

mother’s parenting time, especially given her significant distance from the

children’s base in the Bettendorf area. This is what causes the friction here.

Faced with these competing interests, both of which are important, the

district court struck a fair and reasonable balance between the two to resolve the

tension. By reducing the number of visits during the school year, the district court

reduced the number of disruptions that could result from any travel associated with

the mother’s parenting time. By increasing the amount of summer parenting time,

the court provided an opportunity for the mother to spend additional quality time

N.W.2d 99, 103 (Iowa Ct. App. 1991)).
 8

with the children to make up for some of the lost time during the school year. We

agree with the court’s resolution of this issue.

2. Activity and Calendar Requirements

The father challenges the district court’s refusal to require the mother to

take the children to their extracurricular activities during her parenting time. He

also asks us to modify or eliminate that part of the district court’s order regarding

use of a Google calendar to plot the children’s activities. We consider the two

issues together, as they are intertwined.

Following our review, we agree with the district court’s decision to deny the

father’s request to require the mother to take the children to all scheduled activities

during her parenting time. While the children’s activities are important, giving the

father control over the mother’s time with the children leaves room for abuse. The

district court found, and we agree, that the father has already shown a tendency

to use the children’s schedule as a means of interfering with the mother’s time with

the children, thereby negatively affecting her time with the children. We trust the

mother will make the children available for important events as necessary. If the

mother unreasonably ignores the children’s obligations associated with a

reasonable amount of extracurricular activities, that is an issue that can be

addressed in a future action. We will not speculate that such unreasonableness

will take place, so we decline to unduly restrict the mother’s parenting time now.

As a subset of that issue, the father also asks for clarification on the Google

calendar requirement established by the district court. We decline to expand on

the requirements as set by the district court. As ordered, the father is required to

place the children’s events and appointments on the calendar so that both parents
 9

are aware of the children’s commitments. As expressed by the district court, the

purpose of the calendar requirement was to help the parents exchange

information. The requirement was not designed to serve as a method for giving

the father control over the mother’s parenting time, or vice versa, and we decline

to disturb it.

III. Exclusion of Witnesses

This issue stems from the district court’s refusal to allow the father to call

seven witnesses. After having heard from the parents, it came to the district court’s

attention that the father intended to call a number of additional witnesses. The

following exchange took place:

COURT: It’s the court’s understanding that the [father] has a
list of other witnesses that they wish to call. Are all of the witnesses
relative to the children’s extracurricular activities and the importance
of these activities in their lives and their skill and abilities in those
activities?
FATHER’S COUNSEL: Yes.
COURT: The court finds the testimony along these regards is
superfluous, extraneous, and cumulative and will not allow the
witnesses to be called as the issue of the children’s excellence in
their extracurricular activities has been established and accepted by
the court. If the [father’s counsel] wishes to make an offer of proof,
she can at the close of the proceedings. Is there any other evidence
that the [father] wishes to present?
FATHER’S COUNSEL: No. I’ll just ask to make the offers of
proof.
COURT: Very well.

After discussion of other matters, the judge left the courtroom and the father’s

attorney proceeded to make an offer of proof on the record summarizing what she

believed the witnesses would have said if called to testify.
 10

A. Standard of Review

The district court has broad discretion on trial-management issues,

including limitations on time and the presentation of witnesses.13 Such

discretionary rulings are presumptively correct and we disturb them “only upon a

clear showing of abuse of discretion.”14

B. Error Preservation

On our own motion, we raise and decide an issue of error preservation that

limits the scope of our discussion on this issue.15 As noted in the above exchange

between the court and the father’s attorney, the father’s attorney confirmed that

the subject matter his desired witnesses would testify to would be the children’s

extracurricular activities, the importance of these activities in their lives, and their

abilities in those activities. With respect to that subject matter, the father preserved

error. However, that is the limit of the issue for which error is preserved. In the

offer of proof placed on the record after the judge left the courtroom, the father’s

attorney expanded on the subject matter that would be covered by the witnesses.

On appeal, the father seeks to have us consider the expanded scope of the

excluded witnesses’ anticipated testimony. This we decline to do.

The father was given the opportunity to call additional witnesses to cover

other topics, but he declined to do so. Further, there is no indication in the record

13 In re Marriage of Vidal, No. 09-1608, 2010 WL 3324939, at *4 (Iowa Ct. App.
Aug. 25, 2010); see also Iowa R. Evid. 5.611(a)(2) (giving the trial court reasonable
control over “the mode and order of examining witnesses and presenting evidence
so as to . . . [a]void wasting time”).
14 Vidal, 2010 WL 3324939, at *4.
15 See Top of Iowa Coop. v. Sime Farms, Inc., 608 N.W.2d 454, 470 (Iowa 2000)

(permitting the appellate court to raise and decide error-preservation issues not
raised by the parties).
 11

that the expanded scope of the subject matter of the excluded witnesses’ testimony

as referenced in the offer of proof was brought to the district court’s attention.

Therefore, the district court was never given the opportunity to hear testimony

about the additional topics. “The purpose of an offer of proof is to give the trial

court a more adequate basis for its evidentiary ruling and to make a meaningful

record for appellate review.”16 That purpose is defeated when, as here, the district

court is given one basis for making its ruling and then, in the offer of proof,

additional bases are given without alerting the court to those additional bases.

Consistent with the purpose of the offer of proof, we limit our review to the topics

that the father told the court would be covered in the witnesses’ testimony.

C. Analysis

The district court has the authority to set time limits and limit the number of

witnesses at trial.17 We find no abuse of the court’s discretion in excluding the

father’s additional witnesses. Much of the testimony at trial centered on the

children’s involvement and success in their sports. In fact, no one disputes that

evidence. Based on the offer of proof and the statements made to the court, the

testimony of the additional witnesses would have simply reinforced uncontested

evidence that was already in the record. We agree with the district court that the

testimony would have been cumulative, and the court did not abuse its discretion

in excluding it.

states that permit a trial court to set time limits and the number of witnesses).
 12

IV. Conclusion

Following our de novo review, we agree with the district court’s decision to

modify the parenting schedule and require the parties to exchange scheduling

information via a shared calendar. The court did not abuse its discretion in

excluding witnesses who would have offered cumulative evidence.

AFFIRMED.
