he goes to sleep fine at 7-7.30pm
Generally sleeps througy (until 4am)
Every day without fail he will wake up for the day anytime between 3.45am and 4.30am
His room is completely dark no light gaps
White noise consistent from bath time through to morning
No noises or anything
Bedtime routine is bath 6.15 asleep by 7ish
Day time nap is around 11-1 or sometimes 12-2 if he can last until 12
So so stuck and out of ideas.
Btw he is not waking up happy in the morning, he wakes up crying and tired but no matter what we try he won't go back to sleep
