Let's face it, kids are brutally honest. For instance I had no idea my butt was so jiggly until my daughter nicely informed me. (OK fine, I knew, but I didn't need it pointed out.)
Kids also say lovely honest things, like, "Mommy, I'm lucky you're way more fun than the other mothers" or "Mommy, I bet when we go out, people think we're sisters."
When my little ones say stuff like that, the result is utter joy, which is why I'm inventing Rosetta Stone (Mother Language Edition). Yep, I'll be putting a multitude of beautiful sentiments (we wish our children would utter) on tape, so we can stick headphones on those kiddos while they sleep.
