I've been doing a lot of reading about sleep training and we'll probably go ahead in the next few months. One thing I'm not very clear on is if it is best to have LO sleep in his own room?

We currently have DS in his own cot bed next to ours, official recommendations say its safest to stick to this arrangement until at least 6 months old (he's 3 months now). I'm quite happy with this as DS wakes up anywhere from 1 to 4 times a night and it's convenient to have him so close by (plus my paranoid first time mummy instinct can check he's still breathing). But would this work for sleep training or should we move DS next door first?

Thoughts and experiences appreciated!
