When I say stretching, he can do 3.5 hours in the morning no problem, it just doesn't seem to work out later in the afternoon. Its like the extra 30 mins combine and catch up with him.
I have been thinking about reintroducing the dreamfeed. We did it up until 11 weeks when we left it one night and he started sleeping through. I mentioned it to DH today but he wants to try and get in more food during the day...rather than go backwards to the dreamfeed as he sees it...but maybe that's not the way to go.
We haven't really tried resettling. We leave him when he wakes (sometimes he does go back to sleep, but rarely) and he will chat to himself for 10-15 mins. We go in when his calls turn to more like cries, and change him. Yesterday we tried giving him some water first - he had been awake for 40 mins then - but he went nuts and wanted the real deal, which he drank. Pat/shhh doesn't work on him any more and it only used to when he was tired, he's WIDE awake when he gets up, so no chance of him dozing off. I wanted to try Pu/Pd today, but as my DH works such long hours, he wanted to go back to sleep, not listen to Caspar cry etc. Maybe we can try it on the weekend when we can catch up on the sleep during the day.
My only remaining option apart from dreamfeed is wake to sleep, and I don't fancy getting up at 4am as I'm afraid he will too - but I guess I can only tell if I try...
