I took Michael in for his check up last week and here were his stats:
12 lbs 5 oz (50-75%)
26" (100%+ off the charts!)
15 3/4" head circumference (50%)
Luke's reaction to this was that he's trying to populate the world with tall asians. :) I now have had a child that's 3 months behind in clothing size (Lily), a child that's right on in size (Arya) and a child that is 3 months ahead (Michael)!!
