I am a chronic over-packer and with baby #3 on the way, I'm afraid I'm going to end up carrying a freaking suitcase with me. While researching "diaper bags for 3 kids", I saw that some of you pack a extra bag and just leave it in your car, and only carry the essentials on you.

So....if this is you....I'm wondering what you pack in each bag? I'm probably totally over thinking this, but again, I'm an over-packer who likes to be prepared for everything. Kids will be 4 (fully potty trained), almost 2, and an infant.
