Sarah meet his playmate Ava, she varies between 5.30 and 6.30 for wake ups after bedtime at 1830, ive tried moving her bedtime and it made no difference at all,just made her crankier in the evening, I do think its her natural body clock, i get up put a few toys in her cot and she plays for half an hours or so, she's always shattered by about 9:30 am and goes back to bed!
