We have a three year old so we sing kiddie songs a lot. One common one we sing is Old McDonald. So my husband and I sing the first part, then my son chooses an animal and we all sing the rest about the animal. Yesterday we were singing like usual and I told my little one to choose chicken. We all are amusingly dramatic at times and I knew he was in one of those moods.
We often find ways to amuse ourselves on car rides. On a side note, I am not sure how I feel about my husband growing chops. -Snack Lady
