When a woman has a baby, she immediately is faced with many decisions. These decisions include, where to send the child to daycare, what kind of diapers to use, or which doctor to take them to.
One of the most important decisions is whether or not to breastfeed. Doctors and nurses around the country suggest that breastfeeding has many benefits. These benefits are not only benefits for the baby, but also benefits for the mother. Breast milk is made especially for the infant. It helps the infant to develop into their fullest physical, emotional, and intellectual potential.
Breast milk contains many nutrients. These nutrients are easy for the infant to digest and automatically adjusts to the infant’s needs. The most important nutrient in breast milk is fat. The baby needs fats and cholesterol for brain and body growth. Another important nutrient in breast milk is protein. This protein is easily digested by the baby and is more completely absorbed than the protein in formula.
