However, Tatoe had his one-year checkup in November. (He was 13 months. Don't even ask.) This is the growth chart the nice doctor showed us. In case you can't see, it looks like he went from about 60th to 30th percentile for weight.
Of course, I was immediately skeptical. This is the CDC chart, which is great for exclusively bottle-fed infants. Breastfed babies tend to pack it on at first and then slow down dramatically after 6-9 months. So, I made a WHO chart, which is based on a more-breastfed population.
And... he's fine. Of course he's fine. He has leg rolls, for goodness' sake. He eats like a tiny, bald hobbit: seven meals a day, plus snacks.
Data: It keeps you from panic.
