Gum?

Luke has been saying 'gum' a lot. Sometimes he says 'a-gum'.

Neither Wally nor I have any idea what he means. We noticed that he says it a lot in the car, but then he will say it every once in awhile at home too.

We are trying to tie anything we can together to figure out what this word means. Is there always music playing? Is it always said after something else? We can't figure it out!

And it doesn't have anything to do with actual gum. He wouldn't have a clue what that even is and neither of us really chew it much that he would really even hear the word.

At least at this point he isn't getting frustrated that we aren't 'doing something' after he says it. Hopefully it will click for us soon, but until then we will just keep nodding and smiling when he says it :)
