just seen your reply
yep it’s like a secret club. No one mentions it until you are so screwed that you mention it. Then 1 by 1 they all break and tell you their own terrible stories.
I come from a large family and know myself and our oldest sibling slept just fine on our own and stayed in our own beds. However the younger siblings did not. My mum purchased bigger and bigger parent bed to cope. (They ended up with one of those emperor beds - 2 king size mattresses side by side!)
if our siblings fell asleep in their own bed they damn well didn’t wake up in it.
so I already had an inkling about it.
my kids are super sensitive. And curious. And have very active brains.
both diagnosed as neurodivergent around 8yo. So not unusual to have a very active brain and to need strong connection with a loved caregiver in order to be able to let go enough to sleep.
they also like routine which is their own routine. Ie not one I’ve forced on them.
I highly recommend the Calm app. Loads of sleep stories. My kids love it.
They often listen to the same story. It’s the familiarity which makes them feel safe enough to sleep. Stephen fry reading the earlier Harry potters or a fabulous reading of the nutcracker.
1 of mine also takes melatonin at bedtime as prescribed by the psychiatrist. Super helpful.
best of luck. Unfortunately I don’t have a magic wand for you. I can say it gets better tho!!
