What is one indication of adequate growth in infants by 4-6 months?

Doubling of birth weight by the age of 4-6 months is a key indicator of adequate growth in infants. During this period, infants typically undergo rapid growth and development, and doubling their birth weight within this timeframe suggests that they are receiving sufficient nutrition to support their physical growth. This milestone is a significant marker used by healthcare providers to assess a baby's health and nutritional status.

In addition to weight gain, health professionals often monitor other growth metrics such as length and head circumference, but the doubling of birth weight is a prominent milestone that reliably indicates a healthy trajectory of growth. Infants are expected to gain significant weight in the first few months of life, and reaching this milestone by 4-6 months reflects proper feeding practices and overall health.
