Are we still worried about percentiles?

Emmy at 30 months is 29 lbs and 34 1/2" tall. This puts her in the 53 percentile for weight and the 17 th for height. My lil girl is a shorty so far! Part of me hopes she gets my height. but not at Grade 4 like I did! LOL I remember feeling SO out of place, and my hope is Emmy doesn't have the obvious reasons for kids to pick on her as I did being tall and fat.
