Mystery Solved!

"Get it" That's what "ga-gah" means! We noticed through Willson's increasing use of the word that he was pointing at several different things. That's why we could never figure out what it was. We decided that it was a word that he made up for anything he wanted. But then someone said "get it" and we heard Willson say "ga-gah" I had an A-ha moment and was thankful that I am able to once again understand my 15 month old. For today anyway.
