ROA or ROP

Describes the position of the baby in the mother’s uterus. The R stands for right, O stands for occipito, the part of the baby that will be born first (usually the back of the head), A for anterior or towards the front and P for posterior or towards the back. So ROA means the baby is lying on the mother’s right, the back of his head is coming first and his back is turned towards the front of the mother or, if ROP, towards the back of the mother.
