The U.S Department of Health of Human Services advises exclusive breastfeeding for the first 6 months and the inclusion of breast milk in the baby's diet until at least 1 year old.

The correct answers are 6 months and 1 year old.

Explanation:

The U.S has different standards than the World Health Organization. The U>s states that the baby should be given breast milk only for the first 6 months of life. After 6 months, the baby can be introduced to solids and kept on some breast milk until 1 year old. However, it is up to each mother and father as to how long they want to breastfeed their child.  

The World Health Organization states the baby needs to drink only breastmilk for 6 months also, but they state they need to drink breast milk up to the age of two and beyond.  

Breast milk is optimal for a baby's health, growth, and all of their nutrition needs for the first 6 months. The baby must be introduced to new foods afterward and not be solely on breast milk afterwards.
