Considering average weight gain, what is typical for infants aged 6 to 12 months?

1. 3-5 ounces

2. 2-4 ounces

3. 5-7 ounces

4. 7-9 ounces

The correct answer is: 2-4 ounces

For infants aged 6 to 12 months, a typical weight gain of 2-4 ounces per week aligns well with growth expectations during this developmental stage. During the first six months of life, infants usually experience rapid growth. However, as they transition into the second half of their first year, the rate of weight gain tends to slow down somewhat. This reduction in the weekly weight gain can be attributed to several factors, including increased mobility as infants start to crawl and explore their environment, which often means they may become more active and burn more calories. Additionally, the introduction of solid foods at this stage can influence weight gain patterns, as infants begin to derive more nutrition from a variety of foods rather than solely from breast milk or formula. Understanding typical weight gain in this context is essential for monitoring growth patterns and ensuring infants are developing appropriately. Regular assessments during well-child visits allow health care providers to evaluate whether an infant is following their growth trajectory and to discuss any concerns with caregivers.
