Breasts require maximum attention after delivery. Breast feeding mothers have to take extra care. Breasts sag if the infant is suckled while sitting or reclining in a faulty posture. For example, sucking with the infant in lap or suckling lying down is harmful for breasts. Always suckle with sitting position with the child in lap and your hand under its head so as to lift it and keep its head steady.
Press nipples immediately after suckling and remove the remaining milk with a couple of jerks.
This helps to prevent sagging. Some women have under developed breasts while some have too large breasts. Many married women have a peculiar problem with one breast being smaller than the other. It is because of suckling the child more on one side than the other. Even some unmarried women develop this trouble.
