That just one bottle can have serious consequences for both the mother and baby? Unfortunately, it is very easy to give a breastfed baby "just one bottle" and the reasons for giving a bottle often show concern and compassion; e.g.,

  1. Letting the mother have a well deserved rest after a long delivery.
  2. Settling a hungry baby who is difficult to feed.
  3. Give the mother's sore nipples a rest.

But studies show that "just one bottle" can be harmful to both the mother and baby by

  1. Increasing the likelihood of serious allergy to cows' milk protein.
  2. Increasing the chance of bowel infection and diarrhea by changing the pH of the bowel. It may take up to a month to return to normal, safer levels.
  3. Causing nipple confusion--having difficulty latching to the breast.
  4. Affecting the delicate supply and demand balance.
  5. Increasing engorgement by not emptying the breasts.
  6. Decreasing the mother's confidence in her ability to feed her baby.
  7. Reducing the duration of breastfeeding.
