My dd is 15 months, will be 16 months on Feb 13. Anyway she is only 29 inches, that's pretty little for her age. All the other babies around her age are around 32 to 36 inches tall! Could something be wrong with her?
She's probably fine. Are you tall? What about her dad? As long as she is following her own curve then there isn't anything to worry about.
Both of mine are giants, but so is Dh and I'm no pixie either so its not surprising.
