How long does my baby need breast milk or formula?

Depends on variables: Breast milk is great comprehensive nutrition for babies for their first year of life. After the addition of supplements around 6 months, the protective value of immune factors begins to decline.By a year, the benefit compared to other sources is near equal.After a year regular milk is ok.Those who breast feed for the first few weeks give baby a great boost, and it remains great nutrition past 1yr.

About one year: After a baby is 12 months of age, and is eating a variety of baby foods, he can be weaned off formula and start whole cow milk. The weaning can be gradual over a week, in which more and more cow milk is mixed into the liquid formula each day. By the end of the week, the baby's drink will be mostly or all cow milk. Or one can wean suddenly, by making the formula disappear and just offering milk.
