The Long and Short on Kids' Height
Tall, short or in between - parents can worry excessively about how their child is growing, and it starts during those first newborn checkups. Pediatricians will expect babies to grow consistently according to the height and weight chart, checking to be sure the two are roughly in the same percentile. The doctor should, however, take into account genetics. If there is a great divide - height in the 90th percentile and weight in the 50th, for example, and parents are tall and lanky, then there probably isn't anything wrong. As she grows, if your child seems shorter than her peers, then again, genetics may be at work. Pediatricians roughly estimate kids' adult height as an average of the parents' height, adding two inches for boys and subtracting two inches for girls. Preemies tend to be smaller than their peers until about age 8, but babies born before the 32nd week may stay smaller.
