You have started doing your little wave – where you hold your hand up about shoulder height and then open and close your hand several times – all the time. Your dad and I joke that it’s the sort of wave, relaxed and almost as an afterthought, that would be accompanied by the words ‘buh-bye’ if you could talk.

Oftentimes you will do this gesture to say goodbye, when you hear the door shut or when I say goodbye to your father. But in the last day or two you’re doing it at random times, sitting in your highchair or while we’re rocking, for example. I know you’re trying to communicate something, but I haven’t quite figured it out yet. I’ve still been trying to teach you the signs for ‘more’ and ‘all done’, but you’ve never signed those back. Maybe you’re using this wave as some sort of sign; I just have to determine for what.
