Over the past week or so I had started signing the word "more" to Kate when ever it was obvious that was what she wanted. Thursday night while I was changing her she randomly signed "more" for the first time so I said it back to her. Seeing her reaction was incredible. Her face lit up and she couldn't stop smiling, she kept repeating herself so I kept saying it back to her. We were both equally excited. It's now Saturday and she is very quick and confident in letting me know when she wants more!
I was able to catch a short video, it's a bit shaky but fun to see her communicate. Guess I need to learn some new words!
