So I am 18 weeks pregnant and have a daughter that is 13 months old.  We got into the habit of letting our daughter sleep with us and now I really want to end that.  I don't want to have to leave her in bed alone when I wake with the baby on nights my husband works really late.  We are at the point where she will go to sleep in her crib but she NEVER stays asleep throughout the whole night unless she is in our bed.  Did anyone else go through this and has advice on how to get her to sleep through the night in her room??
