Co sleeping fail

Jessica
My daughter has been in my bed since birth. She's now 4 😁
She has her own room. I let her pick everything out so she would feel like it was her own room and bed. She refuses to even sit on it to play. I'm currently 25 weeks pregnant with number 2 and don't know how I will function if I can't get her in her own bed. Any help? Suggestions? Anything. I'm desperate lol.
