Similac 5g No. 4 is a follow-on formula designed for infants from 6 months onwards. It is formulated with a unique blend of nutrients to support your baby's growth and development as they transition to solid food. It contains added iron, calcium, and vitamin D to support your baby's bone development and immune system.

On the other hand, Similac Neosure is a specialized formula designed for premature or low birth weight babies. It is formulated with extra calories, protein, vitamins, and minerals to support the catch-up growth of premature babies. It contains higher levels of calcium, phosphorus, and vitamin D to support the development of strong bones.

When it comes to choosing between these two Similac products, it's important to consider your baby's specific needs and consult with a healthcare professional. If your baby was born prematurely or has a low birth weight, Similac Neosure may be a more appropriate choice to support their growth and development. However, if your baby is already six months or older and starting to eat solid foods, Similac 5g No. 4 may be a good choice as a follow-on formula.

Ultimately, the decision of whether to buy Similac 5g No. 4 or Similac Neosure should be based on your baby's individual needs and the advice of a healthcare professional.
