TJ has learned how to whistle.
I'm not even sure how he learned to whistle. Is the kindergarten playground a breeding ground for lip pursing and blowing? Just what are they teaching our kids these days?!
I don't whistle very well - truth be told I whistle better on the inward breath than the exhale. My son, however, is a little tune generator making up little ditties as he goes about his day. They don't have any rhythm - he just makes them up as he goes along. And that's the most beautiful part of it.
I don't know where music inspiration comes from but it's neat that there is a song in his head and in his heart always ready to get out.
