Carter finally signed "more"!
I was brushing his teeth and had just finished my first go-round (I usually do two) and stopped to wipe the drool from his face and my hand. Then I noticed him putting his hands together and realized he wanted me to keep doing it!
I thought maybe it was a fluke and he was trying to clap or something, but last night he did it again. I was feeding him some pasta from my bowl and we finished it and I told him it was all done. So he put his hands together and signed for more. Of course I had to oblige!
