I am due to have baby number 2 in a few weeks and over the past few weeks our daughter has become more and more difficult at night. She goes to bed absolutely fine and goes to sleep for a few hours in her own bed. She then wakes up and demands to come into our bed. We've tried calming her and putting her back into her own bed several times on the trot but it doesn't work. We've tried bribery. We've tried staying with her in her room but really all she wants is to come to our bed with us. She just screams and screams (the other night screaming til she made herself sick - she threw up all over the bed, the floor, the rug, everywhere). She's otherwise an extremely secure, happy, outgoing and fabulous girl. It's just the night-times which have become a nightmare. Help!
