The charts the writer is referring about have 0% to 100% and actual heights and weights associated with those percentages. So in fact, according to those growth charts, the child can be > 100%. I know these charts because my child was less than 0% on these charts and we monitored his height and weight like a hawk and ended up in the feeding clinic. (but very easy to carry my child -- only at age 8 is he getting too big to carry --47 lbs)
No they don't. There are no charts with 0% or 100% lines. People assume the top and bottom lines are 0 and 100 but they aren't. They are usually 1 and 99, or 3 and 97, although you might find one with other lines.
My kid was under 40 lbs at 9 (Z score below negative 4, weight below the 0.1% ile). So, I know about outliers and about interventions for weight.
