Bye bye

Addison said "bye bye" tonight. We were getting ready to go up to Chuck's work to show a friend of mine's brother the jet. As we were getting ready to leave I said to Addison "Let's go bye bye to see Daddy!" Her response was "bye yi." Good enough for me. Than she said it again as she walked to the car. It was sooooooo cute. So now instead of saying "bye bye" we say "bye yi" now. I have a feeling fully formed words are right around the corner and than Lord help us...
