You might think that I just won the lottery, or that Lucas said Mommy or something. No, but after a good 6 months of signing milk to him, he signed it back to me today, and I am seriously on top of the world. I thought I was just imagining things, but he did it a few times. I even got it on video, so I hope you enjoy. Watch his right hand very carefully! This is a big milestone, because it indicates that we have bridged the communication gap with him, and he knows that language exists. What a joyous moment.
