Okay, posting for a friend... she is relaly having some problems keeping her 2yo DD in bed... Before when she was in a cot she was sleeping 6pm to 6am going straight into cot and sleeping...

3 weeks ago when she put her into a bed, DD started to wake 3-4times a night, and take anywhere from 5mins to 1hour to get back to sleep... My dear 35week pregnant friend is very exhausted... And would like her Dd to go back to her normal sleeping patterns before her DS arrives...

Any tricks to the trade to get her DD to stay in bed? and sleep?
