It's important during breastfeeding to watch your baby intently and observe his body to determine when to change breasts. "Breastfeeding is a symbiotic relationship," says Leigh Anne O'Connor, New York-based certified lactation consultant. "In many situations, a baby will pull off when he is satisfied." If he doesn't pull away on his own, O'Connor recommends switching once your child has softened the first breast by breaking the latch and offering the other breast to the baby. It’s also a good idea to burp him before offering the other breast, she says.
