I moved my 4 and a half month old into his cot just over a week ago. From 10weeks old he slept the night through. I have always contactnapped throughout the day. I decided to try and stop them as I moved him into the cot using it for naps too. Now he doesn't sleep through the night wakes constantly from 230am. Wakes as soon as I pit him back in the cot. I'm at a loss on what to do to get his sleep routine back
