Lie on your side with your head on a pillow. Nestle your baby close to you, with her head in the crook of your arm, her mouth level with your nipple, and her tummy against yours. When you and your baby are comfortably situated, you'll need to get her latched onto your breast correctly. If she isn't, she won't be satisfied with her meal, you may develop sore nipples, and your breasts won't produce adequate amounts of milk. First, bring your baby to your breast, not your breast to your baby.
Babies can breathe well even if the tip of their nose is compressed.
When you offer your breast, support it with your fingers underneath and your thumb on top. Then stimulate your newborn's rooting reflex by tickling her lower lip with your nipple until she turns toward it with her mouth open wide. Making sure that your baby's tongue is down, center your nipple in her mouth and pull her close to you. When it's time to switch sides, slide your pinkie between your breast and your baby's gums to break the suction. When you hear a soft pop, extract your nipple from her mouth and position her on the other breast.
