I've mostly co-slept with my 8 month old since birth, and it never been a problem. He sleeps the first part of his night in his own bed, and when he wakes up I bring him in bed with me and bd. Last night I half-woke and didn't see him and went, "oh, duh, he's in his bed." Later (I don't know how much later) I felt something digging into my back and realized I was laying on his hand and kind of squishing him.
It really freaked me out, because I didn't even realize (in my sleepy haze) that he was in bed with me and he was under the cover and didn't have much room between me and bd. I checked his breathing, really worried than I had smothered him (another online mama I talk to just lost her baby--I think that impacted my paranoia a bit).
Does anyone have any thoughts in increasing co-sleeping safety? Am I overreacting? He's not a newborn, he makes noise and can move around if he's uncommfortable, but god, it spooked me.
