Joe and Delaney are getting great at keeping themselves occupied these days. They love their exersaucer and bouncy seat, and we recently pulled out a walker to see how they would do. Joe is getting around nicely (thanks to the hard wood floors), while Delaney's toes barely touch the ground. :)
We're confident that she'll catch up. In the meantime, she spends part of her day talking to the toys on the exersaucer while her brother does circles around her.
