Why Do Parents Need to Feed Their Babies Infant Formulas? 

Undoubtedly, mother’s milk is the most nutritious diet for babies less than 2 years. However, some parents may decide to feed their babies infant formula instead of or along with the mother’s milk. There could be many factors behind it such as decreased milk supply, the mother’s poor health, and the baby’s feeding issues. Here are some common reasons parents choose to feed Similac Baby Formula to their babies:

Breastfeeding Difficulties

Adoption or Surrogacy

For parents who adopt or use a surrogate, an infant formula may be the only option for feeding their baby.

Some mothers may choose to breastfeed and supplement with Similac baby formula to ensure that their baby is getting all the necessary nutrients for growth and development.

Allergies or Sensitivities
