Thanks, I've actually tried a later nap, and if it's more than 5.5 hrs after wake up, then he doesn't sleep as long. He's usually in bed by 6.30 and I really don't want to make that earlier, it's kind of tough at the moment to get dinner, bath, wind down in there as it is. If he wakes at 6am it'll all good the schedule is fine (his sister has to be ready for school out the door at 7.30) but I'm just not sure what to do when he wakes at 5am
