Yet another set-back with 2.5 year old

[MatchsticksForMyEyes]

I've stopped his nap as he wasn't really showing signs of tiredness and had started waking at 5ish after previously sleeping through.
I split up from my husband nearly 2 months ago and we've been in a rented house for about 5 weeks. He was sleeping fine, then this week has started waking in the middle of the night and not settling. Screaming like he's really scared, so I've put him in with me, where he's chatted for a bit before dropping off.
Tonight it was like he was scared of his cot. He didn't want to lay down. In the end I had to resort to playing lullabies through the monitor as I did when he was a baby. I don't want to leave him inconsolable, but wonder if he is playing me. But then, what if this is him processing what has happened with me and his dad and he needs that comfort? I am just knackered on work days though as I am getting broken sleep every night and then by the time I get him settled I only have a couple of hours before I have to be up for work.

Just been through a week of this with my DS (2.3).

He was suddenly fearful at night, at his worst waking every hour and crying out for me.

I put his gro clock onto nightlight mode and told him that bunny was looking after him (his favourite toy) and that he doesn't need to be scared. After 2 nights of this he's gone back to sleeping through.

Not sure if its the same with your DS but maybe worth thinking about?

He has a gro-clock that always worked a treat before. After the battle I had trying to get him off to sleep he then slept through til 6.15. Can't work him out!
