I am 25 weeks pregnant. Does anyone have any tips for preventing sleeping on your back? I go to sleep on my left but at some point at least once or twice in the night will wake on my back. Obviously I’ve no no idea how long I’m like that and would hope it’s not long - something always wakes me be it instinct (?) or needing the loo or something. I’ve always got a pillow behind me but it doesn’t really help. Any ideas!!?
