I want opinions. Not rude comments. No bashing. 
Just your opinions , your stories , your experiences , and if you have done research or even talked to professionals about it. 
 Ok so. The topic? 
Bedsharing with preschool aged children. 
My husband is from Egypt. And there apparently they sleep with their kids for friken ever. 
Anyways. My daughter will be 5 in march. She has mostly been in her own bed and room for a few years. I slept with her till a certain age and then she was migrated to her own room.
Recently she keeps getting in bed with us. I take her back to her room. But he insists on letting her sleep with us. We have a kind sized bed and yet she still will turn her body sideways so she takes up the entire bed. I can't deal with that. Firstly I'm in to much pain right now and barley sleep. Second this is my bed. My space. My only space to myself. And my husband. I may sound horrible but why the hell should I have to share everything. I'm a mom. But I am human and need my own alone time and space. 
He says I'm going to make her hate me. She needs to feel loved and safe. 
She will start crying some nights when we say bedtime and say she's scared but she has night lights. She sleeps n there all the time. And she can never produce the thing that she's "scared" of. She knows how to manipulate people. She knows he is one of those people she can. I stand my ground and he gives in. 
I don't see how I could be harming her by making her sleep in her own bed. 
   Not to mention I'm two days away from having baby brother who will be in a co sleepernin the bed with me. So there's absolutely no room. So she shouldn't be let sleep with us because in a few days it will be impossible and she's going to freak out even more. 
I'm just frustrated and I wanna know everyone's opinions and stance on co sleeping with kids her age
