A few weeks ago, DD (3 in a couple of weeks) started waking really early - I’d say around 5 is the average but there’s half an hour either side of that.
It throws the whole day into chaos as she’s flagging big time by 3pm and is desperate to go to sleep by 5. I normally manage to get her to bed by 630. If she does end up napping she won’t go to sleep until really late and then is still up at the same time the following day.
she has blackout blinds and the only change I can pinpoint is she’s in a toddler bed not a cot.
(Please no advice on gro clocks etc as the problem is her waking up so early not staying in her room. She also absolutely does not go back to sleep in my bed.)
