What's going on??

My little chunker butt just had her 2 month check up and she's an average length at 23in and in the 90th percentile of weight at 12lbs 7oz. CHUNKER BUTT!! I realized she was getting "heavy" when I was giving her a bath. I was finding rolls inside of rolls...and gunk in the rolls. How nasty is that? GUNKY ROLLS!! My first thought was " I'm a bad mom!" My second thought was, "how in the world is this non mobile child getting so much gunk in her rolls (and between her toes and fingers)?" Seriously, she eats, sleeps, and poops. Not only is there gunk in her rolls, but eww dirty fingernails! Do you have a secret walking life in the middle of the night where you go outside to dig holes in the yard child?
