Want to preface this with saying that I love my MIL, she's a kind and caring woman and an excellent grandmother. But she's incredibly sensitive and very difficult to talk to about anything that could be interpreted as criticism.
Our nearly 3yr DD is in a particularly wilful phase at the moment, there is a lot of shouting "NO" very loudly, and she is somehow simultaneously incredibly clingy to me while also wanting anyone and everyone else. Think clinging to her friends mum's at playdates and losing her shit if I come near her, but also losing her shit if I leave the room. Honestly, it's been pretty upsetting, but I've been trying incredibly hard to keep it all bright and breezy and keep my feelings about it to myself. DD is also very sensitive and gets very upset if she thinks she's done something wrong, so while I try to correct the yelling and hitting, I don't bring my emotions into it, because when I do DD gets really upset and feels whatever toddler version of guilt and shame, and it lasts for hours and I really, really do not want that for her.
Enter MIL. We're there for a few days. DD's behaviour has actually been really good, but she is all about Nana all the time and it's been quite hard for me to basically be told to get fucked by my toddler 24/7. But hey, that's life.
The issue is, every time DD does this, Nana tells her that she's upset mummy and hurt mummy's feelings, that mummy is sad now, and that she has to go and tell me that she's sorry. DD then feels really bad and withdraws and I honestly can't stand it. If she shouts at me and hits me, she gets told of for doing that. But I'm not comfortable with telling her off for wanting Nana to do her hair instead of mummy. Yes it hurts my feelings, but that's a me problem! I want her to feel comfortable expressing her preferences and boundaries, I want her to learn to do it politely and to understand that sometimes needs must, but I don't want her to feel bad for doing it!
MIL has a habit of turning everything into a guilt trip, with everyone, but I can see how much it upsets DD and I really don't know how to phrase it so that she stops. Nor does DH.
