If you're chunky and you know it

Today was Zack's 2-month checkup. Sweet little guy did great, even with shots. Ready for his stats?

Length: 24.25 inches. 95th percentile!

Weight: 14 lbs. 1 oz. 95th percentile! And up 5 lbs. 6 oz. from birth. Wowza!

His head is measuring in the 75th percentile, which is funny because he's not at all like his big bro. Brett was off the charts his whole first year.

Ready to guess? Here are pics of both boys at 2 months old...who is who?
