She insists on putting him to sleep for his nap when I visit, which I oblige to. But then sometimes plonks him on the sofa bed that's downstairs (other grandchildren use it when they stay over). She's with him most of the time but does wander off to 'get things done'. Her argument is that she listens out for him.
He has only been walking for a few weeks now and when he's half asleep he can crawl off our mattress at home (it's on the floor as we co sleep) without even making a sound. So I know he could so it there and fall off the sofa bed. Admittedly it's not a very big fall to the floor but I just don't feel comfortable with it.
Just had yet another run in with her regarding this and she said if I trust her to look after my son I should let her do things her way. I argued that ultimately I am his mother, regardless of whether I trust her or not, and I basically want it done my way, which was to place him on a makeshift bed I'd made on the floor. That way, no one has to be constantly there watching him. Also I would have happily stayed with him myself but I had to go to an appointment today.
I do give her free rein over pretty much everything else when she's with him, but felt too strongly about this to let it go.
AIBU? And am I overreacting re: the sofa bed?
