At 7.5 months old my petite daughter is just 14 lbs 14 oz and 26 inches long. She is the cutest little shrimp!!! She mostly sits up by herself, blows raspberries, spins in circles on her belly, and does a cute inch worm type crawl to get things. She loves to scoot herself under her brother's chair where he drops food at every meal. Even when the floor is clean she still goes over there to see what she can find. She also likes to get over by the back door to play with the vertical blinds.
