My daughter is little. She's 26 lbs when she's fully clothed at 3 years old. To put it in perspective, there's a little girl who is also 3 years old that came into my work and she's 45 lbs! 19 lbs heavier and an inch or two taller. While I do think my daughter is on the slight side, I think 45 lbs is a little on the ....errrr...husky side. Most kids her age are probably in the 30-40 lb range.
If you try to determine where most of her weight is, it's in her head. We cannot get any shirts over her big ol' fat head. Torso is about average. Legs are incredibly skinny, and we have to pull all her adjustable waist pants in, and they still sag on her. The bottom half of her is almost non-existent.
So I take her to her first movie today. She's very excited. We get our tickets, and I put her into the seat next to me. The problem is that her legs are so light that they can't hold the theater seat down. It keeps folding in on her, so her legs are forced up to her nose. And then she starts slipping down the huge gap that occurs when the seat folds in on itself.
"I'm stuck, mama!"
"I'm falling, mama!"
I suppose the solution is that until she is weighty enough to not fold in on herself, I have to hold her.
