Warning... Long rant coming!
Dd is 4, almost 5, and goes to a 30 minute ballet class on a Saturday morning. Dh takes her, because I work Saturdays - I literally have nothing to do with it.
Months ago dh mentioned that the whole dance academy (they do loads of different classes) were going to put on a show at the local theatre. Lovely.
2 weeks ago he gave me this Saturday's date and said I would need to book a ticket. It's at 7.30, he can't come because he has a gig. No problem.
Last Sunday I found the schedule. Dress rehearsal tomorrow at 5. (I finish at 5.30, as does he) she needs to be at the theatre in full make up. I've managed to find a mum whose child is also going who is willing to take dd. She is also going to pick her up from school instead of her going to after school club and do her make up. Brilliant. She will be home at 9.30. (She is usually in bed by 7)
Saturday she needs to be there for 5pm, and dh can drop her, I will pick her up, and again she will get home about 9.30pm, but the real killer is Sunday.
She is to be dropped at the theatre for 2pm, first show is at 3pm. Then she has to stay there and do another show at 7pm. She can take snacks, but nothing greasy, nothing hot, nothing with chocolate, no nuts, (fair enough) nothing that could mark her costume etc (including fruit) and no gadgets, eg iPad or DVD player.
I knew nothing at all about Sunday's shows, and the tickets are all sold out now, so nobody will be in the audience for her. 
Aibu to think this is too much to ask of a 4yo. She's only in one bloody song (out of about 20). Each performance is 2 hours long, plus all the waiting around, and no parents allowed in the dressing room.
Would I be completely unreasonable to feign an illness on the Sunday and have a lovely day doing something else with her? I'm working most of half term as it is, I only have the bank holiday weekend with her and she's going to be shut in the green room for most of it.
So cross with dh for not looking into it properly. 😡
