Ready to Feed Formula

Preparing Similac® Ready to Feed formula is easy. Just twist off the cap — no mixing or measuring — and the formula is ready for your baby.

Heating

Formula doesn't need to be heated. If you choose to feed warmed formula, don't microwave it. It can cause "hot spots" that could burn your baby. Instead, heat the water in the microwave or on the stove, and then place the bottle of formula in the hot water until it's warm. Sprinkle a few drops on the inside of your wrist to make sure it's not too hot (or cold).

Storing

If your baby does not drink directly from a nipple-ready bottle, you can store the opened container of ready-to-feed formula in the refrigerator for up to 48 hours. See the label for specific instructions. (Be sure to twist the cap back on.)

Reusing

If your baby doesn't finish a bottle of formula within one hour, toss the leftover. Don't save it for later. During a feeding, your baby's saliva can contaminate the formula in the bottle. Once this occurs, reheating or refrigerating won't kill the bacteria.

If you heat the formula, and your baby decides not to take it, don't refrigerate it and reheat it again later. Throw it out instead.
