Ds is 22 pounds at 17 months. That may not sound tiny, but it seems so to us, especially compared to his twin sister who's 26 pounds and 90% for height and weight! Since ~6 months, ds' weight has ranged from 5-7 %ile. He is 60% for height. He eats like a horse, but he's just an active little guy I think.
I'm pretty much over my panic mode that set in a year ago (almost exactly), and have almost come to accept that this is just who ds is meant to be. But I do worry sometimes that he's not getting enough calories, especially now that we're entering that toddler phase. He's self-feeding with a spoon, drinking from a cup, and doing pick-ups... and when they say they're done, they're done - no wheedling, no cajoling. I'm trying not to make food an issue, kwim??
In some ways, it was easier to stuff him to the gills (figure of speech) when I was spoon feeding him baby food. He'd just eat and eat. Now he eats what he likes, and then that's it. As I said, he still eats really well (more than his sister who's 26 pounds and 90% for height and weight!!!) but I do worry about what I'll do if the "picky toddler" phase sets in.
In writing all this down, I realize that I have been a little worried about protein and iron intake for both dd and ds, and I've heard iron deficiency can cause slow growth. Dd and ds eat like they're vegetarians - whole grains, fruits/veggies, cheese... almost all organic. They like fish and chicken, but neither is high in iron. OK, I'm going to start another thread...
