Feeding your baby formula and breast milk together is not recommended under normal circumstances. If you breastfeed exclusively, it is the best thing you can do for your baby.
Unfortunately, there are a few times when a baby has to be supplemented with formula. In some cases, feeding babies a combination of breast milk and formula is necessary.
Always remember though that breast milk is the number one choice, then the second best is donor breast milk and lastly formula!
Ultimately, it is your choice what you do, but here are the facts…
Possible Disadvantages of Supplementing with Formula or Water
* An artificial nipple may cause nipple confusion (suck problems and refusal of the breast) This usually occurs, if a baby is younger than 6 weeks when the artificial nipple is introduced.
* Supplementing will decrease milk supply. A baby might not drink from the mother as much and therefore her supply will decrease.
* Supplementing breast milk, may lead to the breasts becoming engorged and painful.
* Most moms who supplement, end up breastfeeding for only a short period of time.
To supplement breastmilk with formula will not help combat Jaundice, but will
make it worse. Breast milk acts like a natural laxative to eliminate
meconium and this helps in lowering bilirubin levels. (A mother should only supplement, if she does not have enough milk)
* Babies can not be treated for Hypoglycemia by supplementing breastmilk with formula.
* The death of the mother means that a baby will need to be either fully formula fed or given donor supplement breast milk.
Supplementation is Needed Temporarily
Stopping breastfeeding temporarily
* Mom has taken a medication that could be dangerous for her baby such as anti-metabolites, radioactive iodine, or some anti-thyroid medications. So in other words, during the time that mom has these drugs in her system, she should supplement with formula or donor breast milk (if available).
* Mom is using street drugs such as heroine or cocaine. (A mother may continue to breastfeed with the use of tobacco and alcohol) While a mom has street drugs in her system, the baby will need to drink formula or donor breast milk only.
* The mother has the Human T-cell Leukemia Virus.
* The mother has Varicella zoster (virus similar to chicken pox) During the infection she can give her baby formula and then continue to breastfeed afterwards.
* Mother has herpes simplex virus on her breasts. Once the sores have healed, breastfeeding is safe.
Babies who Cannot Drink Breast Milk
* A baby with Galactosemia (rare condition in which a baby cannot digest galactose in breast milk.)
* Babies with PKU who cannot tolerate phenylalanine.
* The mother is HIV positive. In some cases, moms with HIV are advised not to breastfeed at all but, in lower standard of living cases, it is sometimes best if a mother continues to breastfeed.
When it is Not Necessary to Stop
Conditions in which breastfeeding should continue.
Hepatitis B, Tuberculosis, Lyme disease and Mastitis.
