Sorry you are feeling so tired. I hope things get a little more settled for you soon.

With our DS he was always wrapped and a good sleeper. As he got bigger he was getting too big for the wrap to keep him snuggly contained and he was always coming out of it and waking up. At about 3.5 months we tried him in a grobag. He hated it and was always banging himself in the face and scratching himself so we'd end up putting him back into the wrap again. For a couple of weeks, every other night or so we'd try him in the grobag again and then one night he just liked it. He went to sleep and we haven't really had any other problems with his sleep since. (unless he's teething).

The other thing you could try is wrapping him with one arm out so he gets used to that. Can you put the mittens on him to stop him scratching himself?

Have your asked your DH to give you a break, say on Sunday, where you can have a big sleep-in and he can look after the kids for a few hours?

Hugs.
