In Law Rant

So I have PPD and just started meds last week. I'm waiting to hear back from the therapist to schedule an appointment. I confided in my MIL about it all. Ever since she has been helping more with our older child (18mo). I am thankful for the help. My problem is they never keep her on her nap schedule if they put her down for a nap at all. They also never give her milk or water. It's juice or lemonade all day. This is not the first time she has come home with diarrhea and I suspect it's from all the juice. It typically only lasts 1 diaper and she never has any other symptoms. And then today the took her to an amusement park. It was her first and they didn't even ask. I'm disappointed I missed it but don't feel like I can complain about it. I'm sure my daughter had a great time so how can I be mad about that? ... I just feel guilty that I have needed the extra help and then missing out on things like that gets me down. My husband is also disappointed he missed out on it, but I doubt he will say anything to them about it.
