3.5 year old just will not sleep later than 5am. He has always slept badly and still usually wakes in the night. Tried earlier bed time for two weeks, later bed time for two weeks, food before bed, black out blinds… every thing we can and it just won’t work. He won’t stay in his room and play until a reasonable time on his grow clock. He’s in our bed jumping around insisting we get up and it’s killing me. Makes me grumpy and intolerant the next day.. just don’t know the answer and why after 3.5 years there’s no change :-( HELP!!!
