Thanks ladies for your replies & I have implemented the suggestions with some success.

Lulu2 & Trish he was up too long as I have been getting him to bed after about an 1 hr & he isn't grizzling as much. I have also been stretching out his feeds which gives me break.

Trish any ides where you hire the hammocks from ??

Clariebear We have been getting up a lot earlier too which means he is getting to bed a lot earlier at night & sleeping for longer periods then because like you said even if you sleep in it is still hard at 10pm let along 1 am.

JojoB & Rosehip_fairy I have been putting him on his tummy & find when I pick him up he burbs but generally I find it hard to burp him but have been more persistent & he will burp at least once after a feed.

I have also decided that I need to relax about the whole bad habit things & cuddle him while he is asleep or let him sleep with us at night & to be honest everyone seems a bit more settled & happier. As I said before thanks everyone we seem to be doing much better!!
