Katie just turned 7 months old and has learned to sit unassisted. She thinks it is pretty neat except when brother sits super close to her (she has learned to fear the boy) occasionally knocking her over. Katie is so loved and gets so excited when any of her siblings pay attention to her. She also loves jumping in her bouncer and is starting to stand when you hold her hands. Brent and I wonder if she will be like Lillie and go straight from sitting to walking. She is such a sweet girl and we love having her in our family.
