I started a thread about this recently:
Here's the link, MIL gave DD a dummy after we got rid of them
Following the discussion between her and I after drop off, she got annoyed and told DH we hadn't communicated clearly with her. He apologised, then explained the situation properly (I was pissed off at him for not being clear! Although he says he described it all, just didn't expressly say, 'Please, no dummies at your house because it will be extremely confusing.')
Now she's saying she won't be able to look after DD without having the option of giving her a dummy- she can't bear to hear her cry. To note, DD is now going to sleep well without it at night, and sleeping through. Naps are dropping... she's 3 soon. I cannot have MIL doing this - we're supposed to be having a talk with her tomorrow, before she takes DD. Feel a bit all over the place tbh, as I don't want to wreck relationships, and starting to think is this a big deal after all? Am I creating a drama over dummies?? (I do not micromanage, she can let her have chocolate, watch telly, whatever... It's not like that.)
I hate this!
