I am a Christmas Tree Growing Up Tall

I am a Christmas tree growing up tall (stretch up tall)
But when I first started, I was this small. (crouch down)
Then I grew bigger and had branches so wide, (stand slowly, arms out wide)
And I made pine cones with seeds hiding inside. (hands for pine cones)
The wind shakes my branches, (shake arms)
And down those seeds fall, (flutter fingers downward)
To make new little pine trees for tinsel and balls. (point hands together for trees, slowly make balls with fists)
