Pre school sleep

[Babynamehelp22]

My son started pre school a few weeks ago and his sleep (and behaviour) has gone down hill. He has generally been a good sleeper but, I’m still up with him now even though he must be exhausted. He will then be up at 5.30am, probably with a wake in the night. He used to sleep 7-7. Someone help me!!! He doesn’t generally nap unless we gah fit in in in the morning

How old?

Normally they settle in a month or two.
Pre school start is a major thing being young.

He was three in June, so a little young for the year

I also have a three year old at preschool. Can sleep anytime between 7 and 10pm. I need to be quite strict with his bedtime every day he can otherwise happily play to 10pm. Usually wakes up at 7am independently of the time he slept.

Normal and will settle with time! He is probably very tired and brain is whizzing!
