So I never really though about my daughters size but now I've began to worry shes too big! Shes 19 months, weighs 32.6 lbs and is 33 inches. She has literally gained a lb since her 18 month appointment and I worry I dont feed her healthy enough. Im 5'11 and her daddys 5'10 so its not like were small people and we were never really skinny until we hit our teenage years. Shes always been off the percentile chart so its nothing new. How big are or were your 19 month olds?
