I forgot to mention - conveniently August had his 2 year check up today so I didn't have to make a special appointment for his fever/crabbiness (which I probably wouldn't have and then he would've just been really ornery and I wouldn't have known why).
His official stats:
Height - 32" (4th percentile)
Weight - 21lbs, 12.5oz (1st percentile)
Lead test came back normal - HOORAY!
