DS has always been a fab sleeper and goes down like clockwork at 7pm every night, as well as having 2 naps totalling 2/3 hours during the day. The past couple of months however, he's been waking to start his day at around 4.30am (he might sleep til 5 if we're very lucky!).
This doesn't seem to change if he has less daytime sleep, for example yesterday at nursery he skipped his afternoon nap entirely, so only slept for 1hr 20 during the day (9am-11.20am), then still went to bed at 7ish. He was still wide awake at 4.37am this morning!
We've tried doing later bedtimes too but that also doesn't seem to make a difference. When he wakes at 4.30, I feed him in the dark then pop him back in his bed with a shush/pat, but he just lies there chatting to himself then getting increasingly louder and more upset until we get him up.
DH seems keen to continue letting him sleep for hours and hours during the day (which he will at home, he'll nap for 2+ hours twice a day if you let him - don't get me started on that one!), but I've started putting my foot down and capping each nap at 1.5 hours max. But at nursery his naps are much shorter and he gets on average 2.5 hours of daytime sleep.
If anyone has managed to read this far and has any suggestions for how we can get him sleeping a bit longer in the mornings it would be much appreciated!
