My parents are Deaf so they use AUSLAN for the boys. My oldest knows a few but we've slacked off lately. He picked up "toilet" first when I was pregnant and going to the toilet all the time. I was doing the sign for toilet without realising.

One of my favourite moments with DS1 was when he was about one. We were on holidays and all the Deaf people sit in a circle down by the river and talk all day. He was standing in the middle copying their signing by touching his hands together.

We've got a great iPhone / iPad app which escapes me. It's an Auslan one, as opposed to baby sign, but it's designed for babies and children. You'll be able to find it in the app store if you are interested.
