Is it a word?

So my Mom thinks I said my first word. It has been debated if it is an actual word. It is in the dictionary. Webster's says it is "used to indicate concern or chagrin at a mildly unfortunate event." That is when I use it. I say it when I drop something- be it food on the floor, my lovey out of my crib or a ball when I am crawling. I say it all the time. I drop things just to say it b/c Mom always laughs when I do. So do YOU think "uh-oh" is a word??

Side note- If you live in Atlanta, the Junior League of Cobb-Marietta is having their annual Mistletoe Market this week -Thurs-Sat at the Cobb Civic Center. It is a great holiday market with over 50 vendors. It is JLCM's biggest fundraiser so come so my Mom has more money to give to the women and children of Cobb County!http://www.jlcm.org/mistletoe.html
