Beep, beep, beep

Collin is so proud of himself that he has learned to walk backwards, look over his shoulder, and continue to walk backwards without running into anything...for the most part. This action is accompanied by sound....like most things Collin does these days. When he backs up, he makes a beep, beep, beep sound that mimics when vans or large equipment is backing up. Too funny!!! He must have gotten this from when I or daddy does it when we are playing cars together. We laugh when he does this so, of course he does it again.
