How many inches are your babies?

mine has had such a hard time growing but I thought his height was okay..

he was born 12/28 at 19 inches and today he is 22 1/2 inches.

in the last month he has finally started gaining on 3/5 he was 8.8 ounces (under birth weight of 8.10)

today he is 10 pounds 10.8 ounces

I just want him to catch up and for this not to be a worry
