sleep

[stripy]

Hi there - i'm new to these boards!
My son is 16 weeks old and is sleeping pretty much through the night which is brill!

But recently, during his daytime naps, he won't sleep for longer than 40 minutes and then starts screaming but kind of in his sleep. He still looks though he wants to sleep and gets upset that he is screaming if you see what i mean.

I've tried more winding, dummy, shushing him, cuddling him, walking in the pram etc.
Has anyone got any ideas?!

Thank you

My DS (12mths) still does this now sometimes.
I sometimes leave him for a few minutes (watching from the door !!) and he goes back off or if he looks like he isn't going to, I lie with him on my bed and really snuggle in and he tends to drop back off that way.
