Have been co sleeping with DS2 (8 mos) who starts off in his cot and then ends up bf / sleeping in our bed.
Has been suiting everyone fine until last night when I woke with a feeling of horror followed by a bump and then horrible crying from DS who was face down on the (carpeted) floor next to the bed (having narrowly missed edge of the wooden bedside cabinet).
He was uninjured and settled quickly but I felt physically sick and heart was pounding for quite some time afterwards.
I usually sleep with a protective arm over him when he's on my side of the bed (i.e. bf on right; when he feeds on left he sleeps in the middle between DP and I) and don't know what happened last night, think he must have rolled over twice to have actually rolled out)
Wondering whether DP should move out into the spare room so there is space in our (kingsize) bed for DS2 and I with a pillow on each edge of the bed (and also DS1 who occasionally creeps in during the night) or if I have to stay awake for nighttime bf and settle him back in his cot which might tip me over the edge of sleep deprivation.
I'd be grateful for any advice (and please tell me I'm not the only terrible mother / cosleeper who this has happened to)
