Day sleeps can be such hard work can't they?

My DS2 would alway wake after one sleep cycle too. He would wake up after 40 minutes of sleep, I could have set my watch by him LOL. What eventually worked for us was I would watch the time when he went to sleep. I would then sneak into his room a couple of minutes before his 40 minute cycle was about to end and I would watch him. At 40 minutes he would stir (he'd sigh and move his head), as soon as he did this (and before he had fully woken) I started patting his tummy. This would help him move into the next sleep cycle without waking up.

I have to say that it didn't work for every nap, but it would usually work for at least one of his naps a day. I kept persisting and then one day he didn't need me anymore, he could resettle himself.

I hope you find something that works for you soon .
