My mother claims that my little sister was 18 lbs at 2 years old. I think she's having hazy memory problems (I am one of 6 kids, so she doesn't always remember every detail the way she thinks she does).

Although my little sister was always on the small side, I don't think she was *that* small! The rest of were were totally average-bordering-on-big.

So, is that possible? 18 lbs at 2 years? I looked at the WHO chart and I *think* that would make her less than 2% if I'm reading the chart correctly, but honestly, that chart is confusing to me, so I don't know.

*I'm thinking she was actually 18 lbs at 1 year.
