My imprecise home measurements put Jonah at the 6th percentile for weight and 12th percentile for height. We'll find out for sure at his 18 month checkup on Tuesday. This morning he had 2 sausage links, a piece of wheat toast, 3 baby carrots, and a glass of milk. His older brother had a glass of milk and 1 bite of toast. I just don't get how Jonah is so small.
