I just need some advice on what's safe to use as a "cot bumper". So my daughter is 8 months old and sleeps in a sleeping bag (she always has, she cannot sleep without it) however I've noticed more recently she has been moving around a lot more in her cot so ends up upside down and side ways during her sleep or when she's trying to get comfortable, I've noticed that when she is doing this even in the sleeping bag she is still catching her legs in the bars of the cot as she's a very tiny petite girl. I'm worried she will get her legs stuck in the middle of the night can someone please help? I've looked at air breathable liners but they are also saying suffocation/strangulation hazard!
