Breastfeeding is always the best source of nutrition for the baby, but sometimes things don’t go as planned, and you may find that you are not able to meet your hungry baby’s demand for several reasons. It could be that you have to go back to work, your nipples are very sore and painful, your milk supply is dwindling, your baby is losing weight, etc. Supplementing your breast milk with formula is safe and works fine for most moms and their babies.

The important thing to making this a success is choosing a formula your baby likes, introducing it moderately, and being consistent. You can start by breastfeeding them and then wait about two hours later to give them the formula when you know they are hungry but not starving. Then wait a few days later and add more bottle feeding sessions.

Supplementation formulas are made with top-quality ingredients that are similar to what your breast milk contains to promote growth and development. These include ingredients like lactose, whey protein, prebiotics, and essential vitamins and minerals such as Lutein, Vitamins D and E, and Iron, among others. They also use non-GMO ingredients, and the more expensive formulas have most of their ingredients organically sourced.

With that understanding, here below are our top five choices of best formulas for supplementing that you can try.
