"I hury my head/knee"

Today we picked up a couple cute ice packs with some dollar store money given to the kids by a neighbor. They really wanted them and I kept hearing,
"Mommy I bumped my head, I need an ice pack"
"My hurt my knee, my need ice pack"
"Mommy, Joshua bumped his head, he needs an ice pack, and my head hurts, I need one too"

I'm sure it will stop pretty soon, and am hoping they help cheer up some sad moments.
