What is the average weight gain per week for babies aged 6 to 12 months?

1. 2-4 ounces

2. 4-6 ounces

3. 5-7 ounces

4. 6-8 ounces

The correct answer is: 2-4 ounces

For infants aged 6 to 12 months, the average weight gain per week typically falls within the range of 2-4 ounces. During this age period, babies are generally transitioning to more solid foods and might experience a different growth pattern compared to the rapid weight gain they experienced in the early months of life. At this stage, weight gain tends to slow down due to a variety of factors including changes in metabolism, increased physical activity, and the introduction of complementary foods. As babies become more mobile and engage in activities like crawling and cruising, their energy expenditure increases, which can also impact weight gain. While other ranges may reflect growth at various stages or for different populations, 2-4 ounces remains the most widely accepted average for this specific age group, highlighting a healthy balance of growth during the transition from infancy to toddlerhood. This information is crucial for lactation consultants and caregivers to monitor baby’s growth and development appropriately.
