Final answer:
Approximately 35.9% of U.S. mothers continue to breastfeed their babies at 1 year of age, according to CDC data from 2018.
Step-by-step explanation:
The percentage of North American mothers who continue to breastfeed their babies at 1 year of age can vary. According to a study conducted by the Centers for Disease Control and Prevention (CDC), about 35.9% of mothers in the United States are still breastfeeding their babies at 1 year of age. This is based on data from the year 2018.
It's important to note that breastfeeding rates can differ across different populations and regions within North America. Factors such as cultural beliefs, access to support, and individual choices can influence these rates.
Overall, breastfeeding is a personal decision for each mother and it's recommended by organizations like the American Academy of Pediatrics (AAP) to breastfeed exclusively for the first 6 months and continue breastfeeding with the addition of complementary foods until at least 1 year of age.
