Matthew's 6 month check up

Matthew got a clean bill of health along with 5 vaccines (yikes!) at his last appointment. Here are his stats:

Height: 26 inches (25%)
Weight: 17.2 pounds (25%)
Head: 44 cm (50%)

He seems like a peanut compared to the others. I don't think I ever have had another boy in the 25th percentile. So I just had to look up the others' weights at this age:

Alivia at 6 months - 15 pounds (25-50%)
Will at 6 months - 22.1 pounds (95%)
John at 6 months - 18.3 pounds (50%)
