Dear Sammy,
Tonight was a fun first. Since you are a growing boy, eating is something that you do a lot of lately. When we finish eating, we say in Chinese, 'Chi wan le'. Translated literally, this means 'I am done eating', but the basic meaning is 'All finished'. We have been teaching you the signs so you can communicate better. The sign for 'All finished' is to hold both hands out and roll them by twisting your wrists. Of course as most babies, you have developed a modified version that suits you more. You only use your right hand held down by your hip, and wave similar to the Queen of England! It's pretty cute. You've been slowly learning to mimic us do this, but tonight you told us all by yourself for the first time. It's been obvious by your body language that you are communicating more, but it was nice to have a clear message in sign language tonight.
Love you,
Daddy
