There are a multitude of infant formulas on the shelves, each one with unique characteristics. There are differences between types of formulas and
brands of formulas, so let us discuss these differences before you make any changes.
Sterilize nipples and bottles after each use for only the first month after birth. If you use well water, sterilize the water by boiling it before mixing it with the formula the entire time the child is on formula. If you use a city water supply, there is no need to sterilize the water.
During the first few months, powder formula is not tolerated as well as ready to feed or concentrated. Make sure to look at each can before you begin mixing it to make sure which you are using. Also get into the habit of checking expiration dates on the formula cans, and never buy formula that is past its expiration date.
Many questions arise regarding the proper amount of formula needed to feed an infant at various ages. The only correct answer is to feed the child the
amount he or she wants. An infant’s hunger is driven by caloric need and thirst, so if the baby needs food and has it available, he/she will take it. Bottle feeding should be similar to breast feeding in that the baby should feed until satisfied. Do not try to get the child to take more than he or she wants, and do not withhold formula if he or she wants more. A few infants will overeat to the point of spitting up, but most regulate their food intake pretty well.
