By the time a baby is 8 months old he or she should be eating solid foods 3 times a day in addition to bottle or breast feedings. Many parents often wonder if the introduction of solids signals the end of bottle or breast feedings. The answer to that is no, not yet. Breast milk and formula contain essential vitamins that are very important to a baby's development and should not be stopped before the age of 1 year. However many parents continue bottle or breast feedings beyond the 1 year birthday.
