So, we've been fostering this (formerly pregnant) cat for about a month and a half and she had her kittens about a month ago--only two of them, a boy and a girl. I was in my room (where we've been keeping them separate from our other cats so momma doesn't feel that her babies are threatened by my quasi-evil female cat) reading this evening and the momma and her babies were just so darn cute that I had to share...

The kittens are in a very rambunctious stage right now--running/stumbling/bumping into things/wrestling, etc. So, momma was getting down in a "pouncing" position and the kittens would shake their little butts and run up and whap her with their tiny paws and she'd roll over and wrestle with them ever-so-gently so that they "won"--reminded me of human parents playing baseball in the backyard with their kids and running at turtle speeds so that their kids could make it to a base without getting out. Just made me smile a bit...hope it does the same for you :)
P.S. If you know anyone in the Phoenix area looking for a special cat or kitten to love (or all of them!), let me know. Finding them good homes has proved more difficult than I thought. I would love to keep them all, but we can't have five grown cats in this apartment and my girl cat hates the mom.
