I am considering offering some formula. Is it really much different than breast milk?
While formula is a safe alternative to breastfeeding, it is best to think of formula as a medical tool to only be used if needed. Formula does not provide all the benefits that breastfeeding can.
Breast milk is a living super-food tailored specifically to your baby. Some babies have a reaction to an ingredient in formula. This can stress their digestive system. They may need to try different formulas. Babies who drink formula may have more illnesses, infections, and digestive issues. They may also have more chance of SIDS (Sudden Infant Death Syndrome), diabetes, and obesity.
