Just read another post which has got me worrying and I know this isn't strictly aibu. We co-sleep with our 11 month old baby, dp, me, baby, in that order. I've got one of those foam wedgy things next to baby under the sheet so baby can't fall out or get trapped under. I sleep on my side turned into baby with my underneath arm stretched out over the top of baby's head. I have a duvet but have it wrapped over me and tucked in my legs and not over my shoulders, baby has a cellular blanket and sleeps in a babygro and vest. I breastfeed. I'm average weight, don't smoke, never drink and am not totally sleep deprived.
We slept exactly the same with older dd and I can't imagine not sleeping with baby (he starts off in cot and comes in when wakes for feed). Just got a bit of fear.
