Old McDonald had a Farm

Gavin has been singing this song for 3 days.

All. Day. Long.

While he tends to just sing the chorus (without announcing what is on Old McDonald's farm), he has finished the song several times. And according to Gavin, Old McDonald has more than just animals on his farm. There are forks, airplanes, hats, Bubbas (his nickname for Pax), dump trucks, and dinners on the farm.

Here's a short video of him playing by himself in the playroom. He just can't stop singing.
