Our son is in the 25th percentile for height, so apparently he will be 5'7" or so!

Our daughter is in the 75th percentile, so she'd be around 5' 5 1/2":

Wow, hadn't realized that if they stay on their current growth curves, our 25 percentile son may still be taller than our 75 percentile daughter! (Keep in mind that I could be completely reading these tables wrong - or the tables themselves could be totally wrong too.)

If your LO stays on the same growth curve, how tall will they be?
