Skin-to-skin will help you learn your baby's cues. It will also increase the level of prolactin you produce. Prolactin is a hormone responsible for helping your body to make milk. Many mothers find that latching their babies is easier when they are held skin-to-skin. It can also calm a fussy baby. If you are unable to breastfeed because your baby is sick or premature, you will have to express your milk. Holding your baby skin-to-skin helps your body make more milk.
