Another sign/word we picked up quickly was BANANA. I was just so surprised a couple weeks ago I picked Little Fingers up at the babysitter and the babysitter said, "look, say 'banana'." and modeled the sign while she said it... Little Fingers did it right away with a big smile on her face! And she still does it - she retained that word and sign!
Here it is a couple weeks later and it's a regular word. We're just stunned with the amount of words / signs she has. The list soon to come! 16 months and we're just amazed!
