Don’t have a lot of time… but will make a couple of quick suggestions…
See if you can find the TV show “Signing Time” – your library might have the videos…
You might be able to pick up some “Baby Sign” books easily that will give you a lot of different signs to do with things that a child might be interested in… HOWEVER – make sure it is one that uses ASL signs!
There are a lot of ASL dictionaries online to look up specific words… they can be good because it is a video… a book has a harder time showing the motion.
There are some more resources (but mostly for older people…) – I know there is a site called something like ASL university with Free ASL courses (not for “credit”) – that might be helpful…
Can’t look up anything right now – baby is crying
