I think Mason has made the switch from signing to talking as his preferred method of communication. Although it's still tough to understand many (most?) words, his little mouth is going all the time. When the word doesn't work and he has a known sign he'll stop and use it. Like tonight. Cindy thought that he wanted his plate taken away by saying "move." He kept saying "mo, mo"...over and over. She took his plate away. He cleared his hands and did the "more" sign (and then got about his 12th helping of meat). Even a few weeks ago he would have just done his sign, so it's interesting to watch him make the transformation into the speaking world!
