I'm of the same opinion about BMI. It's worthless. Especially for healthy toddler.
Someone in that doctors office had to have made a mistake and were too busy or out of it to compare the "risky" number with the actual healthy child.

Being overweight is usually pretty obvious. I was once told that my middle child was "at risk for overweight", even with an explanation of his very healthy diet, his obvious active behavior, and the fact that we can count his ribs, front and back. When I pointed out how ridiculous that was, only *then* did the person say "Oh, yeah. Maybe you're right, let's recheck the numbers." Lo and behold, even by the numbers he is at a perfectly healthy weight.

The only explanation I have for that is that they were looking at me--The Fat Mom--and projecting.

Also, my youngest two were 100% breastfed and complete butterballs. They were off the charts in weight from birth through first year. But it was proportionate to their height, and thank God I have a rational pediatrician who never mentioned anything about "risks" because of weight.
The obsession with numbers is just ridiculous. The numbers don't help anything. If a kid is sedentary and eats a poor diet, it's obvious he's "at risk" without any numbers at all. So change the habits, don't harp on the numbers.
