Sleep seperation anxiety

[Trixie87]

Hi hoping for some advice my son is now 10 months and we’ve had a good sleep routine established throughout however for the last month he has been a nightmare to get to sleep in the evenings at first we thought it was just because he was teething and eventually it would pass however it’s still ongoing. I’m pretty sure it’s separation anxiety. But not sure what to do, previously we could just put him straight in his cot and within 10 mins he would be asleep and he still does do this at nap times oddly. But at bedtime he just refuses to settle unless we stay in the room with him until he falls asleep but then he wakes up in middle of night at least 2-3 times a week and again refuses to settle for ages. He’s been able to self sooth from 2 months old so not sure why he’s suddenly started being unable to do it and n the evenings anymore. Does anyone have any tips on how to handle this as I don’t think it can be good to stay in room constantly with him think it’s making bad habits.

Does he have a dummy or comforter or anything? What is his bedtime routine?

What's he doing when he wont go to sleep? Is he standing up in his cot? What are you doing to settle him?

What is his daytime routine like, in terms of feeding/eating and sleeping?

No he’s never had a dummy I don’t like them. I’ve tried given him comforter doesn’t work. He does stand up in his cot he’s up and down constantly. I’ve tried laying him back down but he’s just sees it as a game so stopped doing it. When it initially kicked off I did pick him up for a bit and rock him for a bit but stopped doing it as I think it hinders ore than helps as he just screams when I stop. So at the minute I just sing to him for a little bit and stroke his head if he’s screaming and when he’s standing up or crawling about in his cot I just sit and ignore him til he stops and lies back down.

His daytime routine is fine he eats well and at same times everyday same with naps. I did try reducing his morning nap to see if that made a difference but it didn’t and just made him cranky during the day.
