I don’t think he’s doing anything wrong. Sleeping with a nine year old isn’t normal and needs to be discouraged. Similarly closing the bathroom door when she’s in there should be the norm and I think he was right to close it. What if a male friend or relative had called round while she was in the bath? Who would be at fault then if he’d seen her naked? And presumably if she’s even too scared to sleep alone then being naked would be an issue for her as well yet it isn’t?
You are enabling this behaviour with your pandering approach, and elbows on the table at mealtimes is simple table manners which she needs to have been taught from the earliest age.
I’d expect this kind of behaviour from a three year old not a nine year old, and if you don’t do something about it then she’s going to really struggle as she gets older, and you’re setting her up for potential bullying by her peers
FWIW I didn’t like sleeping alone as a child and had an over-active imagination. And part of the not being able to sleep alone IMO had to do with the fact I went to boarding school and always slept in with others in shared rooms, so when I had to sleep alone I hated it so I put the radio on. By continually sleeping with her you are encouraging the notion that it’s ok to not want to sleep alone.
Also, I used to be afraid of films and scary programmes etc. Entirely irrationally. Then one day my dad told me that if I was going to let my imagination run riot over this stuff he would simply prevent me from watching it. He never did and I grew out of it, but pandering would have simply made it worse.
I do believe that in this country we give in far too readily to this kind of thing, and a lot of what is a normal fear growing up we escalate into anxiety through our own approach towards it.
Your DD needs to be sleeping in her own room, alone, at nine. And she needs to have the bathroom door closed and the audio on at a decent volume which doesn’t disrupt the entire household. And bathing with the door shut needs to be non negotiable. It has nothing to do with her body her choice.
