My step son who we have two nights a week has a new thing about waking at 1am.. That's it now until.. Possibly 5-6am when he will go back down for a nap until 10am. Both us and his mum are concerned that there's a problem (her first, I have no DC of my own) as he literally changed from one day sleeping 7pm-9am, to this new 'routine' the next a few weeks ago.
Anyone who can give me advice as to whether this is normal at this age? Or how to handle it, I've tried the leaving to cry, brought him into bed with us, the only thing that stops him is getting up with him?
