how far gone are you?
you can sit on it, very comfy i baby is very low down.
you can kneel on floor and rest your arms on it, and your head if you like. good for getting back to back baby to turn. opens the pelvis.
also in labour you can rock on it, do figure of 8s and do the kneeling against it thing. comfy.
then when you've had the baby you can use it in lots of ways to excercise your core muscles.
AND your baby might like laying on his tummy on it, it's like floating. obviously you'll have to hold it steady or he'll roll away , and best put a towel under him so he's not laid on the plastic.
enjoy.
