"Uh, Oh" and "Thank you!"

These are AB's new words. Last week, after something falling or dropping (which happens frequently) off of AB's highchair tray, I replied with "Uh, oh!". The next thing I knew, she was trying her best to say, "Uh, oh!" However, it comes out a bit like, "Oh, oh!" So cute! Then yesterday, AB, Joey and myself went over to visit GG. GG, in her high-pitched, enthusiastic voice, would say, "Thank you!" to AB every time she would hand her something. The next thing we noticed, she was saying something that sounded very much like, "tat-to!" It's so neat to hear her respond to things! She's just growing up way too fast!
