When it's been too cold to go outside and play in the snow, we've done some snow activities inside. Some of our favorites have been having snowball fights with cotton balls, making snowflakes, and singing "Once there was a Snowman." This is a fun, active song for little ones that we learned through the children's programs at our church.
Here is a video of Isaac doing the actions. (If he looks a little stiff it's because he was really nervous about being filmed. Silly boy! Usually he can't get enough of performing for the camera!)
You can also check out the sheet music (and print it for home use) or listen to the song here.
