I am losing my mind

She has been taking one 30 or 20 minute nap every day for the past week and waking between 4-4.30am...I really do not know what to do anymore

We were trying again for a SEBT tonight and she has been screaming for over an hour. What on earth can I do

. She is refusing early naps, or taking ages to fall asleep and then napping for 30-40 minutes. Then she will not take a nap later on at all, and takes an hour most nights to settle.
She is getting more and more OT that I just do not know how to get her out of it as she will just not sleep properly for naps *or* nights, will not be APOPed and is just in a complete state.
I'll post our 'routine' tomorrow to see if anyone has any thoughts, as DH did her nap today so I don't know the exact times - just that it took her an hour to settle (from 11-12ish) and she slept for 30 minutes

....again.
Sorry, I don't even know what anyone can say
