DS nearly rolled off the sofa at 4 weeks old (YES early, was rolling with ease at 8w old). I wouldn't trust him alone in a bed for a minute.
I am thinking of taking the bars off now, not next to the wall but the side so he can get out of bed in a morning. He can safely climb down from my bed (higher up) and the sofa so it would be good to have him play in his room in the morning! But getting him to bed would be a problem then... or would it? I wouldn't have to lean over the bars to get him to sleep. May talk to DH about this at the weekend. But he's still waking up at stupid times in the middle of the night... but that could be because he's hitting the bars... which would mean he'd fall out of bed... but it's usually a trapped foot... AAAAAH decisions!
I started off with a moses basket then went straight to cot bed. This way I don't need to buy a "big boy bed" until DS is 5-7 (depending on height) and I'd go for a bunk bed with desk/sofa underneath then because those are SOOOO cool and I always wanted one. Oh yeah, and friends could stay over and he has space for homework and playing without taking over the house. I'm practical about it, I promise. Oh yeah, and I can climb in the cotbed when DS is really unsettled. I have to curl up my legs but I can snuggle with DS until he goes to sleep which you can't do in a normal cot.
DS will also sleep anywhere, in any cot. Travel cot fine, cot provided with a holiday home fine, my mother's cot she bought for him fine. It's the individual child, not the bed, that makes a child sleep anywhere.
