Baby : Formula

If you’re a new mother, you already know that breastfeeding is best for your baby. But not everyone can successfully breastfeed. What’s important is that your baby gets the nourishment he needs to develop and thrive. If your baby isn’t thriving on breast milk, then you need to switch to formula. There are many different options to choose from.
The brand you choose isn’t important. All formulas are prepared according to FDA regulations which specify minimum and, in some cases, maximum nutrient level requirements for infant formulas, based on recommendations by the American Academy of Pediatrics Committee on Nutrition. These regulations and the Infant Formula Act help to make sure that all infant formulas are nutritionally complete and safe for your baby.
The American Academy of Pediatrics does not endorse or recommend that your infant drink any specific brand of formula if you choose not to breastfeed, except they do say that low iron formula should not be used.
Baby formulas mostly differ in the type of sugar and protein that they have. Regular iron fortified infant formulas, such as Similac Advance, Enfamil Lipil, and Nestle Good Start Supreme are made with lactose and cow's milk based proteins. Most infants who are not breastfeeding exclusively should be given a cow's milk based iron fortified formula.
Soy formulas are made with soy protein and are lactose free. They are good for children who don't tolerate lactose or milk proteins.
Elemental formulas are also lactose free and are made with hydrolysate proteins, which are easy to digest for infants with protein allergies. If you have a family history of food allergies or formula intolerances, you might choose to start your baby off with a soy or elemental formula if you do not want to breastfeed.

Baby : Breastfeeding

New parents want to give their babies the very best. When it comes to nutrition, the best first food for babies is breast milk. Experts recommend that babies be breast-fed for six to 12 months. The only acceptable alternative to breast milk is infant formula. Solid foods can be introduced when the baby is 4 to 6 months old, but a baby should drink breast milk or formula, not cow's milk, for a full year. Cow's milk contains a different type of protein than breast milk. This is good for calves, but human infants can have difficulty digesting it. Bottle-fed infants tend to be fatter than breast-fed infants, but not necessarily healthier.
Human milk contains at least 100 ingredients not found in formula. No babies are allergic to their mother's milk, although they may have a reaction to something the mother eats. If she eliminates it from her diet, the problem resolves itself.
Sucking at the breast promotes good jaw development as well. It's harder work to get milk out of a breast than a bottle, and the exercise strengthens the jaws and encourages the growth of straight, healthy teeth. The baby at the breast also can control the flow of milk by sucking and stopping. With a bottle, the baby must constantly suck or react to the pressure of the nipple placed in the mouth.
Initially, a breast-fed baby will need to be fed 8-12 times in a 24-hour period, especially since both baby and mother are getting used to the process. Breast milk is more quickly digested than formula, which is another reason why more frequent feeding is necessary. Another reason for the constant suckling at the breast is to stimulate the mammary glands to produce more milk for the baby’s growing appetite. But the extra time spent feeding the baby that first year is well worth it as breast milk passes along the mother’s immunities and delivers the highest-quality nutrition for a developing baby.
