Accomplishments of a 10 month old

Gunner is 10 months old today.  Wow time flies.  Dr K. questioned me at his 9 month check up that 1) he wasn't holding his own bottle 2) He wasn't getting up on all fours 3) he wasn't really rolling a lot and 4) he hasn't sat up from being on his belly or back.  Being 25.12 pounds I told Dr K. he was just too chubby to roll and sit up.  Chad and I were just fine with him just sitting there being happy and being served by his brothers.  Well that appointment must have done it with Gunner.  Two weeks later he was sitting up from back or belly, holding his own bottle, becoming quite more active rolling everywhere and at 10 months he is crawling.  He is even starting to pull himself up to the couch.  We are so proud of him and all his accomplishments.  It is so fun to have a baby in the house and wonder what goes through their little heads.  Keep it up Gunner we are proud of you.
