I've kind of decided to try to learn some basic ASL signs to use with babysign, since one of Stella's day-care children is 4 months and the other is 2 and just starting to speak... and since I'll be speaking English to both of them, ASL kind of makes more sense than DGS, especially since I won't be signing in complete sentences to them anyway (I expect) so it doesn't matter so much if I don't have a proper handle on the grammar. (Though that's a weak justification; based on what I speak to them, BSL would be even more appropriate, if anything. But ASL seems to have the best available Internet resources.)
So far, I've found SigningSavvy as a sign dictionary.
Amy can already recognise a few signs (at least eat, drink, cat, baby) I showed her.
I think I need a signing userpic; perhaps me fingerspelling my name or something. And I wonder whether to use "duck" as a namesign based on my Martin userpic, which I use nearly everywhere one can upload one's own avatar. (He's my Gravatar, for example, and I think also my Facebook profile picture.)
