Pediatric nurse here. Since 1989.

That happens all the time from about age 3 to 6.
I found it to be most common at the 5 yr check up.
Babies should triple their birth weight by one year.
7# , 21 inches at birth
21# , 30 inches at first birthday.
Then the weight gain slows down considerably- as the
height continues to increase at a more rapid rate.
At two years of age a child may weigh only 30# but is USUALLY already 1/2 of what their adult height will be. A 36 inch 2 year old will end up approx 72 inches (6 ft)
You end up with 38 inches 38# at 3
44# 44 inches at 5 (or 6) etc...
As kids age their height ends up beng less than their weight
and it stays that way for life.
*this is just a general rule for growth and does not apply to ALL children!
DNA does factor in as well as the height and weight of the parents
just a lil FYI
