This has a lot of life to it for a haiku. I LOVE this. Great work and keep writing.

This provides a very nice image of fall morning or midday

suggestion for the last line:

In the breeze kids play

which: links the fluttering leaves and the playing kids to the breeze...

Good work: keep on writing

Such a sparkling image...a short tale of forgotten innocence, at least that's what I got out of this...
