Integrating 6 month old into 3yo's room at night???

Hi There,

My 6mo DS is still sleeping in our bedroom as we live in a 2 bedroom house and it's so not working as he's noisy and we are also waking him when we roll over or use the bathroom etc. As much as I want to integrate him into his brothers room (almost 4) I'm petrified they will start waking each other all night. Bub is still having one night feed and unfortunately waking a couple of other times too (I think he's used to us being there). Also my oldest sometimes takes about an hour to get to sleep and plays silly buggers in that time so not sure little one would get off to sleep with this going on...

I'm at a point where I am starting to not cope with the lack of sleep. It's been months since I've had more than 4 hours sleep in one bracket and I'm due back at work soon and can barely string a sentence together (seriously, it's taking me forever to type this as I keep making errors ;-)

Anyone got any advice or anyone else been this situation? The helplines suggest bringing our 3yo into our room for a few nights and letting little one sleep alone but I think this will just create another problem..

Many thanks!
