I'm on maternity leave and once a week MIL comes over to watch DS for a few hours.
I sleep in a bed beside DS's cot in the nursery and DH sleeps in the master.
Because my bedroom is also technically "the nursery" my MIL feels she can go into it as she pleases.
Her argument is she needs to be able to put DS down for his naps but the time she regularly comes doesn't overlap with his nap times, I always put him down before and after her visits.
She may need to go in there occasionally to get a muslin etc but I feel she needs to be more respectful and only go in when necessary.
DH has had to explicitly tell her not to lie in my bed. She's constantly taking things out of the nursery and scattering them around the house.
But the other day she really pee'd me off - DS was still napping when she came - I was alone in the kitchen and saw him cry on the babycam, I walked into the nursery to find her half on the bed with her face up to him. I thought she was in the living room! He did his scared "wtf" cry and I said annoyed "oh...hello..?!" and DH, also annoyed, asked her to leave (he works from home).
She said "he was already awake" but that's not the point!! I feel like a teenager shouting at my mum (in law) "get out of my room!!"
AIBU?
