@junipermints If I'm understanding, you're saying he normally has every other weekend, and your train of thought is:
If he misses one weekend, he should have the next, then just resume the every other weekend schedule from that point on?
Example:
Origional schedule
Weekend 1: dad
Weekend 2: mom
Weekend 3: dad
Weekend 4: mom
Weekend 5: dad
Weekend 6: mom
But then he misses, say, weekend 3. So you think that missed weekend should result in alterations and wind up looking something like this:
Weekend 1: dad
Weekend 2: mom
Weekend 3: (dad cancels) mom
Weekend 4: dad
Weekend 5: mom
Weekend 6: dad
...and so on
If that's your expectation, OP, then yes, you're both "taking crazy pills," AND this is fair.
I completely understand where you're coming from, in the sense that you just want him to maintain a consistent relationship with her, and don't want your daughter to suffer any negative feelings as a result of going several weeks without seeing her dad.
However, just flipping the whole schedule moving forward is NOT common practice. And while it may not make much of a difference to you in this season of life, flipping the whole schedule moving forward as a result of one missed weekend will likely become very problematic in the future.
Consider these scenarios:
1. What happens when you plan a vacation with your daughter, that spans what's supposed to be "your weekend," say 4months in advance, but because of a missed weekend between when reservations were made and when the actual trip is going to occur, a weekend gets missed, then made up with your "Do the next weekend, then just continue the flip-flop schedule from that point on," scenerio? All of a sudden, his weekend falls in the middle of your planned trip.
- As you mentioned, your daughter's social and extracurricular schedule will become busier as she gets older. If dad is unwilling to facilitate her participation in these things, due to distance or whatever, one of 3 things will need to happen: either he will have to give up his weekends (or at least part of them) more frequently in the future; or she will have to learn that she has to decide between spending her weekend with her dad, or doing whatever other activity is occurring on that weekend; or you may reach a point where dad is unwilling to facilitate her participation in activities on his weekends BUT ALSO is unwilling to give up his weekends- in which case, she'll have to learn and inform any coaches/ leaders/ friends, etc that she's unable to participate in things on his weekends (and although this is frustrating, having a set schedule so you/ she can see what his weekends are, to be able to inform what commitments she can/can't make, will ultimately be more helpful than a 'well we don't know if that will be a mom weekend or a dad weekend yet' situation).
I'm sorry you're having a difficult time with schedules; and I'm sorry your daughter is wondering about her dad's commitment and interest in her- her feelings are totally understandable and valid! (Don't forget to tell her that!). Empathizing with her will benefit her more than trying to fix the cause of the bad feelings. You can wish dad would priortize his time with his daughter more; but unfortunately you can't control the decisions he makes.
