How do I know if my baby's latching on correctly?

It should not hurt when your baby latches. If it hurts, it means your baby is not latching correctly. Your baby should be swallowing in a rhythmic manner and her body should be facing you. Try to squeeze your breast in a "sandwich" shape with your fingers to fit your baby's mouth. http://sg.theasianparent.com/latching-and-unlatching-during-feeds/
