i posted nearly 3 yrs ago i am glad my post still gets used, my midwife said it was the babys joints cracking as she moved, i didnt think it posible, but when my 8ib 12oz cubby daughter was born, when she moved her joints clicked, the midwife said where she was floating in the sack it was ecoing,
that was nearly 3 yrs ago and her joints still click now and again as like mine do.
