Situations that affect breastfeeding

In this chapter:

Twins

Twins should be breastfed just like other babies. Remember, the more a mother breastfeeds, the more milk her body will make. A mother can breastfeed both babies at the same time or she can breastfeed them one at a time.

A mother with twins will need more rest, food, drink, and help from her family and from you.

Small babies and early babies

Most small babies and early babies need breast milk. If the baby is too weak to suck from the breast, a mother can remove her milk by hand and then feed her baby with a cup or spoon until the baby is strong enough to breastfeed. Learn more about caring for small babies.

Breastfeeding while pregnant

It is safe to breastfeed while pregnant or to breastfeed an older child and a new baby. The mother should eat even more food and get plenty of rest.

The new baby should always be fed before the older baby.

When the mother is sick

It is usually best for a mother to keep breastfeeding even when she is sick. To prevent becoming more sick, the mother can:

  • drink plenty of fluids.
  • lie down while breastfeeding.

Family members and friends can help the mother with her chores so she can rest.

Medicines

If possible, breastfeeding mothers should not take drugs or medicines. But some mothers who are sick must take medicines. These women should use medicines that are safe to take while breastfeeding.

Most of the medicines listed in this book are safe to take while breastfeeding. A few that are not safe are marked with this symbol in the Medicines Pages.

HIV and breastfeeding

Mothers who are breastfeeding should protect themselves from becoming infected with HIV. Pregnant women and mothers who have HIV should get on treatment as soon as possible, to protect their health and prevent HIV spreading to their baby.

No one knows for sure exactly why a mother’s milk sometimes spreads HIV to her baby, and why other mothers with HIV do not spread HIV in their milk. HIV passes more easily during breastfeeding when:

  • the mother is recently infected with HIV or is very sick with other infections. There is more HIV in the mother's body then.
  • the baby is given formula or other fluids or foods as well as breast milk.
  • the mother has cracked nipples or the baby has thrush in her mouth.


Even for mothers with HIV, breastfeeding is usually the safest way to feed their babies. This is because in most places, formula and other milks cause babies to get sick or die from diarrhea or malnutrition. Especially when mothers are on treatment for HIV, more babies will die from formula than will get sick or die from HIV passed through breastfeeding.

To make breastfeeding safer, help women with HIV:

  • Get on treatment for HIV and take it consistently. Be sure to give recommended medicines to the baby too.
  • Give only breast milk for the first 6 months. Formula, teas, and other foods or drinks can irritate the baby’s intestines (insides) and have neither the nutrition nor protections against illness that breast milk does.
  • If you have enough food to give your baby, make that the baby's main food after 12 months. But you can continue to breastfeed as long as the child wants to.
  • Position the baby correctly for feeding to avoid cracked nipples.
  • Treat thrush, cracked nipples, and breast infections right away.
  • Women with HIV should not feed the baby from a breast that has mastitis or an abscess — instead, remove the milk and throw it away.

A woman whose HIV is well controlled by ART medicine is unlikely to pass the disease while breastfeeding.

Heating breastmilk to prevent passing HIV
Breast milk can be heated almost to boiling to kill the HIV virus. A baby will not be at risk of getting HIV from this heated milk. Heating breast milk takes work, but it can be done if a woman has clean water, fuel, and support.

How to heat breast milk

1. Place a jar of breast milk in a pot of water. Breast milk should not be boiled.
2. Bring the water to a boil.
3. Immediately remove the pot from the heat. Heated milk should be used within a few hours.
4. Let the milk cool before feeding it to the baby with a cup or bottle.
