Hi, have recently been reading and talking to people about sleeping positions am 16w and a few people have said it is really bad for baby if i sleep on my right side or my back. I sleep on my left for a bit but then feel the need to move and am now lying there paranoid that being on my back is bad but get stiff neck if i stay in one position. Have got a sleeping pillow and tried pillows down back to stop rolling but am now swamped by pillows and still not sleeping - am I nuts or does it matter how i sleep?
