Another question...

I found a good site that shows Auslan signs, I learnt I love you, mummy, Jett, breastfeed but I just read on Deaf kids Australia that they run sign language classes. Is it worth it? It is $90 for the baby sign one.. Actually I couldn't do it anyway, classes are from 6 -8pm.. I couldn't have bub out in the cold and can't leave him with anyone.. I guess I'll just teach myself
