hi ibelieve,

how far are you now? you must be getting quite big

the main reason for not sleeping on your back is because the weight of the baby can put pressure against the veins and nerves on your spine,and that doesnt really happen until you are really big. but you will get to a point when it is uncomfortable and you shouldnt wake on your back anymore, but i wouldnt worry about it, i have always been a belly sleeper and i slept on my belly until i was about 30 weeks i would fall asleep on my side but my hips hurt so bad i would always wake on my belly, and jacob is absolutely fine
