My DS 5 months has stopped crying in the night for milk. He is formula fed. However he does wake me up through wriggling and shifting around with the odd little sound. Sometimes I can successfully rock his cot and he will quieten back down to full sleep, only to fidget around again an hour later. I never know if this is hunger, or whether I should try getting him back to sleep without milk to get him used to it now he's getting older. Last night I fed him one feed at 5am, but was awake every 2hrs with all the wriggling. How do you know what to do, when to feed and when to leave him?
