As a recovering OCD mom, I've learned how to let go a little and enjoy having my kids help in the kitchen.  Of course there are times when all 3 of them are arguing over who gets to add which ingredient, or who gets to stir. And every single time, there is a little extra flour or other cooking ingredient spread across the counter (or floor), but thats all a part of their learning experience, right ?  I actually do still cringe a little on the inside when I see every single measuring tool or bowl being used, or when the mess seems to have reached the living room, but I have to say that my kids LOVE being in the kitchen and in the end, that is well worth it!
