Many people get scared during the first few months after a baby is born. They think that even though they are feeding a baby for the first time, they must feed them for as long as it takes. This couldn't be further from the truth! Breast milk is appropriate for babies from birth until around 2 years of age, but it is not meant to last forever. In the case of breast milk, it is not a question of how long you should feed your child; it is how long your child should continue to take breast milk. There is no fixed rule regarding how long a baby should remain on breast milk.
