Ideally and actually most often, the baby will be in an anterior position facing your spine at term, or turns anterior during labor for childbirth. It is important to know when your baby moves into the optimal anterior position, so you can encourage the baby to stay there, which usually means an easier and shorter labor.
You can learn on your own what position your baby is in. But if you are unsure, ask your practitioner for help figuring it out. Then try to pay attention to your baby’s position, without getting needlessly obsessed about it. This is easier to do when your baby moves or when momentarily lying on your back. It may take a lot of concentration to understand what is what at first, but soon you will get the hang of it.
When your baby is posterior, your tummy may look flatter and feel more squashy, and you may feel arms and legs and kicks all over the front towards the middle of your tummy. The area around your belly button may dip to a concave, saucer-like shape, and you may also experience long and painful practice contractions with a more severe lower backache as your baby tries to turn around to the anterior position to engage down into the pelvis.
When your baby is anterior, the back feels hard and smooth and rounded on one side of your tummy, and you will usually feel kicks under the side of your ribs. Your belly button will normally poke out and feel firm.
Pay attention to your posture and positioning at the time when your baby may be starting to descend into your pelvis, which is during the last 6 weeks of your first pregnancy, and the last 2-3 weeks of your subsequent pregnancies. The goal is to make room for your baby to assume the optimal position for birthing.
