H and I have a system at weekends. We each have a lie in on one of the days, while the other gets up, does all child related stuff, breakfast etc.
We have been doing this for the last 8 months or so, and up until now, if for any reason the usual routine is disrupted (I have a lie in on Saturday, he has a lie in on Sunday) then we just take it on the chin. Eg, I had to get up early (stupidly early ie 4am) on my lie in day when we went on holiday recently. Such is life. I didn't get a replacement day, or ask to swap it, it's just how the dice fell.
In January, dd2's Saturday ballet class time changed. She now needs to be there by 9am. So not much of a lie in for me anymore, since I either need to be up to take her to ballet, or I need to be up to supervise the other dc if H takes her. Again, no complaint from me, that's the way life is. My only comment was to ask H to make sure everything was done by the time I got up, as I didn't want to be finishing off getting dc dressed, or sorting breakfast etc, on my lie in day.
So, earlier this evening, having put the dc to bed, H turned to me and said 'so, since it's Mothers Day on Sunday, do you want to keep your lie in as tomorrow (Saturday), or swap it for Sunday?' (Implication being if I keep it as tomorrow, then I'll be getting up on Sunday so he can have a lie in!)
AIBU to think this is a bit crap? He isn't working at the moment, so doesn't have to get up and get going particularly early in the week. I get up all week with the dc, sort breakfast and school stuff, do lunches, and take dc on school runs. He gets up and wanders about a bit, and may help with teeth cleaning, but that's it. And now he is resenting the fact that I might get an 'extra' lie in on Sunday (which isn't even an extra one, given I don't really get one on Saturday given the ballet time change).
