My baby is 5 n half months.his height is 68cm n weight is 8.3 kg.birth weight was 3 kg..is it average?

His recumbent length: & his weight are each 75th %ile for his age, with birthweight ~ 25th %ile. Review the velocity of head & body growth on his growth charts with his pediatrician at each check-up. The aap also recommends that pediatricians do ongoing developmenta surveillance using standardized screening tests at each check-up + autism-specific screens at 18 & 24 mos.
