Formula-fed babies gain more weight than breast-fed babies, but experts say they don't know whether this is true for all types of formula.

In a recent study published in the Pediatrics journal, researchers assigned 2-week-old bottle-fed babies to either take a formula based on cow's milk or a protein hydrolysate-based formula.

Both formulas had the same amount of calories.

Babies who drank the cow's milk formula gained weight faster.

But infants on the protein-based formula consumed less formula during a feed compared to the cow's milk formula.

Experts say they are now trying to determine why infants overfeed on the cow's milk formula.
