So long story short my DD (2 years, technically 27 months) has never been a great sleeper. We finally got her to sleep through the night by bringing her into bed with us usually about 5am. In our bed she would sleep to 7am. Unfortunately, this has now backfired (I should have known) and now she won't sleep in her bed for more than an hour and 1/2. She wakes up screaming her head off right at an hour and 1/2. if we get for back to sleep in her crib it's only for another hour. If we put her in our bed..no wake ups, even when we are not in the room with her. I think she knows are bed is more comfortable. I tried getting a form mattress pad for her crib but that didn't work. I am at a complete lose at what to try next. Help...please.
