20 minute naps hell

[Frazzled2207]

My nearly 7mo is a crap napper and sleeper.

He wakes after 20-23 minutes and if I'm there the actual instant he starts twitching I can sometimes resettle for another 20m but I also have a 2yo so usually I can only get to him after he starts crying by which time he's wide awake.

He sleeps 3 x 20 minute naps each day either in cot, car or pram. Is better at night but wakes at least twice for feeds then we have to
Resettle after 20m. Clearly his sleep cycle is only 20m, his brother's was 45m which I thought was bad enough.

Separately he is unable to settle himself without crying but is getting a bit better the more times I leave him.
It's tough though because he doesn't want to be cuddled/rocked to sleep, yet is happy to be cuddled up to me in bed

Any ideas ladies or will he definitely grow out of this...am sick of listening to mums saying their babies sleep for
3h naps!

On the plus side he is a relatively happy baby during the day despite crap naps, only grizzles when settling for his nap and immediately after waking (as if to say he wanted to sleep for longer)

It seems a little saddening that he can only go to sleep when crying. I prefer a dummy for no crying independent sleep, but I fear 7 months is too old to be introducing a dummy. Will he suck on anything? Comforter toy, blanket, his fingers?

I have tried a dummy since he was tiny, he won't go near it. I have comforters but he's not particularly interested either.
He's not crying as much these days but still wakes after 20m.
