Hi Gina,
First, congratulations on your new baby!
It sounds like you are on your way to being well prepared!
I am a retired Braille teacher and have been taking an ASL class for a few weeks. I would be happy to practice with you sometime. I will send you a video after I figure out how to use this system. It may take me a few days.
Post a list of the baby vocabulary/signs you have learned so that those of us who wish to contact you will have something to get us started.
