At Jack's one month appointment (he was 5 weeks, 3 days old):
Weight: 11 pounds, 4 ounces (up from 8 pounds, 12 ounces at his 2-week check)
Height: 22 inches
He's 75-90th percentile for weight, 75-90th percentile for height, and 25-50th percentile for head circumference.
Which seems odd. His head is very large and round. Very Winston Churchill.
