Sorry a few bits to this...
Our Daughter is 8 months old and has never been a good sleeper, naps and night times. Serval times my MIL has brought up letting her cry it out which both me and my husband have told her we don't want to do.
Anyway she is due to go to nursery when she is 1 but we can't afford for her to go everyday so the MIL has offered to have her once a week. She has asked that she starts to look after her once a week from now so they can build up more of a relationship (with covid we haven't been able to see them anywhere as much as we normally would have, and our baby is very clingy most likely due to the fact she's hardly got to know anyone other than me and my husband)
She has looked after her twice and both times I've come to collect her my daughter has been in tears lay on the playmat in the middle of the living room, really crying and my MIL hasn't been in the room. I know this as the window is looking out on the driveway so I can see in before she even knows I'm there. I've no idea how long she's been like that but when I've gone in my daughter has been in a right state. I'm really reluctant to send her again and haven't told my husband why but he clearly knows something is up.
AIBU to not want to send her again?
I've not spoken to my MIL nor my husband, I'm just someone who really hates conflict.
