My 15wk old son goes to bed after his bath and feed at about 6.30pm. He usually wakes twice for a brief breastfeed, and gets up about 5.30-6am. There have been a couple of times where he gets up at 4am- like today! He's almost totally breastfed, and refuses to sleep more than 30mins in the day (if that)Any ideas for keeping him in bed longer in the mornings, or am i hoping for too much?!
