Aside from helping with contractions, the increased levels of this hormone in both mother and child foster feelings of attachment and affection. On the other hand, another hormone prolactin works together with oxytocin during pregnancy to produce and release breast milk, respectively. It increases during labour with the highest level occurring during birth and remaining high as the mother breastfeeds. Beta-endorphin and adrenaline are other hormones that help in child birth. Adrenalin helps in labor as it gives the mother energy to push. It also prevents the rise of oxytocin when the mother feels anxiety, tension or fear during labour.

It also helps in releasing prolactin during labour so the mother’s breasts are ready for the new born.
