In infants up to age 2, what is the chest circumference relative to the head?

Explanation:
In infants up to age two, the head tends to be larger in circumference than the chest because the skull and brain grow rapidly in the early years while the thoracic cage expands more slowly. This makes chest circumference typically smaller than head circumference during this period. As children grow, the chest catches up and can become closer in size to the head, but in the first two years the head remains relatively larger. So the chest is not greater than the head, not equal, and not twice as large.
