The stats are in...

McKade and Journey each had a Dr. appt. on April 21st. McKade had his 18 month appt. and Journey had her 4 month appt.
McKade
Height 31 inches
Weight 21 lbs. 3 oz.
He is in the bottom 5% on the charts. He has always been in the bottom 5% so as long as he stays on his curve, they don't worry.
Journey
Height: 20inches
Weight: 7lbs. 5 oz.
She is (as the doctors put it) in the less than 5%. Basically, not on the charts. That is to be expected though and she is growing up. She started rolling from her back to her tummy now, and she has been going the other way for about a month.
