My baby sleeps in a 3 sided feeding cot attached to my bed to make night time breastfeeding easier. He has started rolling now so I'm worried about leaving him to nap in his cot during the day in case he rolls out (I know he would have to roll a long way out if the cot and across the bed but it's possible). Does anyone know if I can get some sort of cot side/ bed barrier that I can use during nap times but can be easily removed at night so I can feed him? Maybe one that rolls across like roller blind or collapses like a concertina?
