I think Carrie knows the sign for milk. Last night she woke up crying, and while I was trying to settle her back down she seemed to be signing “milk”, so I picked her up and fed her. Then this morning she started signing “milk” first thing, but I needed to change her diaper first. When I finished changing her, I asked her if she wanted milk, and signed the word “milk”…and she signed it right back to me!
Carrie’s first year sticker calendar doesn’t have a sticker for “first sign”. But, I really think she’s starting to get the concept of language, which is incredible to watch.
