It's horrible isn't it! I was the same, oscar has been in his room a few weeks now but we never intended putting him there until he was six months but it happened by accident! He was outgrowing the cot next to me and I was worried in case he had a growth spurt and didn't fit in it! So I sorted his big cot Bed out, lowered the mattress etc while my mum was here so I had time to do it and I tried him in the cot just to see if he liked it and he fell asleep! Never looked back and now it's the best thing, I can't imagine him back in with us now, we would be far too noisy! He sleeps much better there(except during his four month regression!) I was glued to the monitor for two weeks though! Good luck!
