Formulas are designed to meet the nutritional needs of a growing baby. Discuss with your doctor whether your baby should have an iron-fortified formula or not. Whichever formula you use, follow instructions carefully. Use a measuring cup to measure the water to be mixed into the powdered or concentrated formulas. Make sure that bottles and nipples are washed and clean before using again.
Some babies are allergic to a formula.
If you think your baby has an allergy, talk with your doctor so the formula can be changed. Hold your baby close with her head up. Don't leave your baby alone with the bottle propped up, and don't put her to bed with a bottle. The baby could choke on the milk. For the first month, infants sleep about 16 hours out of 24.
