The little man is thriving. Well, he's still in the bottom one percent for weight, but he is gaining weight like he should. Woohoo and whew! Apparently, the bigger concern was that he had fallen off of his growth curve recently. At his four month appointment, he was in the seventh percentile for weight, but at his six month appointment, he had falled to the bottom one percent. Bad.
Today, he is still in the bottom one percent but he has not fallen any further off of the curve, which is great news. Must continue to stuff the little man. And, after five minutes of watching the little man, our pediatrician proclaimed that his small size is probably metabolic, i.e. the little man is so active that he burns what he eats. It was good news.
