1) Josie just learned to sit down from a standing position. This sounds obvious, but it's a big deal because until yesterday she would get "stuck" standing (i.e. in her crib in the middle of the night). Now that she knows how to sit down, she's standing over by the couch pulling up, then plopping down on her bottom & cracking up over and over again. So funny!
2) Josie has started to "sign back" and use her favorite sign that we've taught her - the sign for "milk." Now that she's officially communicating using sign language, we'll start to teach her more. :)
