My chunky hunk, is sitting up for short periods of time! Rolling back and forth both ways! Teething like CRAZY! He loves to watch the colors on TV, he is wearing 9/12 month clothes! & we are eating baby food & have been on formula for a month now. We are still growing up and happy so that's all that matters!
