The signs we have now for B are more, potty and all done. I am working on the ones I used a lot with K. These include yes, no, eat, drink, bath, tired, home, tissue, nappy, sit, stand, walk, bag, happy, sad. we also did lots of animals to go with the books we read. K always loved orange. At one point he could use it with the right direction to say either the colour (out) or fruit (facing in). He could never say orange and just today at nearly 3yo and having been using sentences for over a year he asked for an "orloon" and did the sign for it. Food nouns are helpful when they are pointing at the kitchen and you ask "what do you want" rather than having to go through the whole fridge/cupboard and freezer etc.
B does the sign for star when he wants to sing too.
