will try that Clare - thanks.
After nursery Monday and the bad nap he was wrecked so bed at 6.45pm and he went through till 6.15am. DH had him yesterday and he napped 2 hours, the first time for over a week and then a good night so I guess this is the way it will be until he adjusts. OT and then catching up. Gonna be very tiring for us all but he seems to absolutely love it so I think I will just have to roll with it. If he does get OT there may have to be some no nursery days to help him out.
