I posted a while ago about a very similar issue but looking for some more advice.
*edit* this most has ended up pretty lengthy.... sorry! Please still read and advise!
A bit of current context-
My LB is 21.5month. He has been in a toddler bed for about a month and transitioned into his new ‘big boy’ room a couple of weeks ago. We’ve made the decision to do this as I’m 6 months pregnant and wanted to move him to allow for any unsettledness to die down before baby comes - however, he has coped very well and after a week of NWs (which also may have clashed with some illness and a language leap) he’s now relatively ok and is STTN again most nights.
My problem is, at the moment, an EW of anywhere between 5:15 & 5:45am. Averaging around 5:30. It’s worth mentioning that this had started happening just before his move into a toddler bed, so I’m not convinced it’s part of his transition. His room is entirely blacked out - he has a gro black out blind in the window and black out curtains, and always has done. He still has white noise playing as a ‘bed time’ trigger and this is always on when he EWs.
He is definitely wide awake at this time - he’s not grumpy or showing signs of needing to go back to sleep. We have a gro clock, that he’s just beginning to understand but not really enough. He gets out of bed and shouts for me - when I tell him to go back to bed and lie down/night night/wait for the sunshine, he does so without fussing. But he absolutely will not stay in bed. The second I leave the room he is back up and at the door. If I lie on his bed with him, then he stays lying down but like I said is definitely wide awake - he plays with his comforter, sings songs to himself, tries to play peekaboo (which I ignore) and sometimes randomly sits up and says sunshine - referring to his gro clock. When 6:00 comes (which is our preferred get up time - set at this hour because of childcare and work arrangements) I make a really big deal out of the sunshine on the gro clock and saying good morning and getting straight up out of bed to start the day.
It seems like he just doesn’t need that extra 30-40mins sleep any more. So then I’m thinking perhaps a routine change? Our current routine is like this:
WU 5:30 (aiming for 6:00ish)
Nap: 12:45/13:00 for 1.5-2 hours
I wake him at 3pm if he is still sleeping - which is quite often the case at home. He mostly settles ok for a nap by 13:00 at the latest, although sometimes doesn’t seem tired enough and wants to play lately. Nursery struggle to get him to sleep before 13:15/30 - they say he wants to play with the other children, which is understandable.
BT 19:00 - he self settled and he always happy to go to bed. He doesn’t get up when left. He is always asleep within 10mins. Mostly STTN.
I don’t think his BT needs moving as he seems to be ready for sleep at that time. But perhaps his nap is too long and is taking up too much sleep?
