Wow, I can't believe Colby is 6 months old. I feel like i always say that but seriously, when did he get so big? 6 month stats.. 18.1 lbs (57%) and 26.75" (58%). Colby is sitting up great, rolling over both ways, loves to stand and jump and he does this crazy thing with his tongue where he sticks it out and curls it up...often. He spends the better part of his day watching his big brother who he clearly adores.
