babies need to be on formula or breast milk for one year. after a year as long as they get all of the calcium phosphorous and other nutrients that are in milk and are eating a good well-balanced diet they do not really need it. milk and milk products (yogurt cheese etc. ) continues to be an excellent protein source and should not be abandoned unless there is a milk allergy or other medical reason to do so.
when babies are switching from breast milk to solid foods is cow's milk neccessary?
