Should your 3 year son who is 3 foot 2 inches in height weigh 2 stone 2 pounds or is he underweight?

Children often go through growth spurts in which they add height quickly before the rest of their body catches up. Since 38 inches is taller than 95% of three year olds, his 30 lb. weight (only greater than 65% of his peers) will probably catch up soon.
