Baby Signlanguage part 1

When I first heard of this,  my wife used to work at a daycare,  I was blown away. Then I saw the movie that had it and was like,  'I can do that!' So I decided that when the baby was old enough I would teach her some sign language.

She was around 4mo old when she learned "done", and I used a trick I had learned from helping raise my niece, Lauren now 13, and was able too teach my daughter to sign done using an ESL and Spanish combination.

I'm not an expert at Spanish, in fact I only know a hand full of words, but growing up, the words I knew, like caca for poop and moco for booger, I thought they were English.

First is "bah". I can't spell it and I'm not sure if that's the correct way to spell it, but I do know its like saying "done" and through repetition I was able to help her begin her communication.  2nd was "food". I would say, "Bah-pah" which I learned as food, although I'm sure it means potatoes,  and did the sign for food. Sure it took a while, but getting to know that she was hungry and when she was done was a giant leap in a direction that changed the difficulty of being a stay at home.

Have you ever taught your child/children to sign? What was the first word they picked up and how old?
