Infant formula may come in power or liquid form. Liquid formula may be ready-to-feed or a liquid concentrate. When preparing infant formula, nannies must follow the instructions on the container of baby formula. Doing so ensures that the formula contains the prescribed quantities of nutrients and calories that the infant needs.
The American Academy of Pediatrics strongly warns against watering down formula. Diluting formula or breast milk may result in water intoxication. It may also slow a baby’s growth and development. Babies feel full by how much they consume, not how many calories they consume. A baby could stop drinking because he is full and not receive adequate calories for healthy growth and development. If too little water is used when preparing formula a baby might develop diarrhea or dehydration.
When preparing formula use a safe water supply. To determine if tap water is safe, it should be tested by the local health department. The American Academy of Pediatrics recommends that when using tap water to prepare formula, it should be brought to a rolling boil for no more than one minute and it should be left to cool to room temperature for no longer than 30 minutes before using. Alternatively, bottled water may also be used for preparing infant formula.
According to the Centers for Disease Control, if a child is only consuming infant formula mixed with fluoridated water, he may have an increased chance of developing mild dental fluorosis or tooth discoloration. To lessen this risk, the Centers for Disease Control recommends that parents use low-fluoride bottled water some of the time when preparing infant formula. These bottled waters are labeled as de-ionized, purified, demineralized or distilled, or without fluoride.
