Ds almost 18 months, sleeps 7pm - 4 or 5 am. This morning he woke at 4, got him.intonbed and he had another hour but up at 5. This is usual. He doesn't often wake in the night anymore but gets up very early.
He's so far spent 3 nights at my parents. Goes to bed a bit later I think, 7.30, but invariably wakes around 6 then gets in with mum and sleeps til 8. She had to wake him up last time. She sleeps in the same room as him, he's in a small travel cot. I sleep then with him every couple of weeks and he sleeps just the same as usual, up at 5.
Mum thinks it's because her house is warmer. I don't because he'd sleep longer when I was there then.
Is it as simple as me being there that gets him up?
