Our DD is 2.5mths and has never been a great sleeper, but since putting her in a bed 3months ago its got really bad. The GP gave me Priton to try which worked for 3nights gave us all good rest. I had hoped it would break the cycle as do not want to give her drugs but change her behaviour. She goes to sleep fine at 7pm then wakes midnight onwards and stays up for 2-4hrs maybe settle by 4am then up to start the day at 6am. My mother in law had similar problems with her DD and mentioned that she had to really watch her diet. No sugar, fruit, sweets, 'e-numbers' after noon. I wonder if other MNs had tried this did it help?. We don't give sweets but she loves fruit.
