Can anyone offer any advice on sleep regression for my 2yo please? He's 25 months now, and since turning 2 things have altered. He's been waking up exactly 1.5 hrs early every morning regardless of what time we do bedtime.
Prior to this he's always had a strong routine and is normally a great sleeper- we've been v lucky!
At the moment the early wake up means he's grizzly all morning and I'm counting down the minutes till his nap! Unfortunately he still wakes up grizzly after his nap and it's same again all afternoon. He just seems tired and needs more sleep. I can't extend his nap and once he's awake after nap or bedtime he won't go back down.
I've tried earlier bedtimes, and also conversely a later bedtime. Whatever happens he still wakes up early, always precisely 1.5 hrs earlier than normal, so at the moment I'm sticking to the earlier bedtimes.
Still he's so grizzly all day. He's also fussy with food since all this started, probably because he's over tired.
It has coincided with settling into a new room at nursery (he attends part-time) which started last week. He's also being clingy which is probably all part of it.
His usual disposition is cheerful, confident, happy and reliable sleeper! So this is all stressful! The mornings in particular I'm struggling with as I used to get up 30 mins before my son to do yoga and it really helped my mental health. Now I'm woken super early with his crying out and I'm spending my mornings trying and failing to get him vs k down! I feel tired and it's miserable.
To clarify we can rule out certain things - eg we use white noise machine, blackout blinds etc, and he has a very strong routine. Teething is all done. When he wakes early I'm going in and patting him down as if it's night time, not engaging him in chat, and only being bright and breezy once it's "proper morning" wake up time. But he's wide awake and will not go back down - cries and cries.
So any tips? I'm sure this is common but I'm struggling with the mornings followed by a grizzly upset tired boy all day 
Do I just wait it out and hope things go back to normal or is there anything I can do? Please help if you can! Thank you 🙏
