MIL looks after DS a couple of days a week but has very different ideas about how to look after a baby to mine and DH. She's said on numerous occasions things like "you can't force a baby to go to sleep!", "if they want you to do something you just have to do it!", "never wake a sleeping baby!" and the like. DH and I both work full time, so have had a somewhat flexible routine for DS since he was about 6 months. Although she rarely says anything explicit, I can tell she disapproves of this. She thinks that I should just let DS sleep whenever he falls asleep but the difference is that she was a STAHM when her kids were very young so had that option.
Anyway, when she looks after DS she seems to make the effort to actually put him down for a nap and not wait until he just physically falls asleep but she has huge problems with waking him up. DH had to actually ring her the other day to tell her to wake him up as it was late in the day and she went on and on about how much she hated it. It makes me feel like we're forcing her to be cruel.
AIBU to just want the baby to not be asleep past 4pm so that he's happy at bedtime and likely to sleep through? I don't want to be ungrateful as her looking after him is a great help to us but AIBU to think that if she's going to then she ought to just follow our rules and stop complaining?
