Query: Why make up words, use ASL

I prefer Joseph Garcia's set. I originally got this book as a gift because family knew I had been teaching my kids Sign. Great stuff, makes for very happy babies that can communicate their needs ( milk, eat, water, change, dog, hear, airplane, help, want, book, etc.) and just "talk" by 10 months old. But, when I got this book, I found it useless, with suggestions of "made up signs". Why not actually teach a second language? Often, I had adults who knew sign approach us and start signing with the babies, how happy and confident my babies looked then! I'd recommend getting Joseph Garcia's set plus a good Signing dictionary, like a pocket one, (for when that one year old wants to know what everything is, in sign) or Joy of Signing.
