I can't say anything, mum is worried that if anything get's said that sister will stop taking the kids round to mums, so then where will they be? Besides, if I said something, I can get in the car and go home and away from it, but my mum is stuck there, I don't want to do something that is going to make it worse for her IYSWIM?
I don't think she is depressed at all, or ill for that matter, she hasn't got a maternal bone in her body. I think a lot of it stems from the fact that her DH's family is very rich, Sis and her DH run up massive amounts of debts her PIL's bail them out, every time she has another baby they give them £10,000 for the baby, last time they renovated their house with the money, not exactly for the baby was it?!! So she has a baby, get's paid a load of dosh, then palms the kids off to my mums and that's it, the cycle starts again.
The eldest practically lives at my mums, he stays there more than at his house, he stayed both nights we were there, Saturday morning, sis brings the baby over for mum to feed him, she hadn't fed him by now, it was 10 o'clock baby was distraught, sister moaning about how grumpy he's been all morning, well durrrrr do you think he might be hungry???! Anyway she walks in, after not having seen her DS1 all night, he was upstairs playing, she didn't even shout up a hello to him, or ask mum if he was OK, nothing. Mum lives close to a high school, sis says when her DS1 is old enough to go to the high school he is moving in with my mum permanantly because it will be easier to get to school, mum lives a 5 min walk from the school, sis lives 7-ish minutes! She doesn't give a toss about any of them, as long as she doesn't have to deal with them, she is happy, and that is all that matters!
