I have a 5 month old daughter (1st) and I want to shout and SCREAM at my 66 y.o. mother in law but feel I have to bite my tongue because she's going to do the babysitting when I return to work at the end of the year. She picks up my daughter whenever she wants, even when my daughter is happy just kicking her legs and gurgling at the telly on her changing mat. Today took the biscuit, baby was screaming the house down and I knew it was because she was too hot, as I went to undress her a bit my mother in law took her off me!!!! I wanted to scream at her "I know what I'm doing!!!" but didn't and baby carried on screaming in her arms as she was making her hotter with her holding her and her body heat. When I first had her she used to ask if she could pick her up but now she doesn't. When my sister in law had my first nephew, I wouldn't dream of just picking him up without her permission! AIBU???
