No one knows busy better than a mom. I’ve got dear friends who have just had twins, and after a day with the infants, I’m exhausted. And I don’t have night duty.

I remember those days as a young mother – I couldn’t even find time to wash my hair, and I would get to the end of the day wondering what I had accomplished.

Well, the answer to that, at least, was clear: I had accomplished getting my own infant through another day, protecting him, nurturing him, feeding him, hovering over him, making sure he kept breathing, surrounding him with love.

Lately I’ve been struck by how much we all buy to keep our babies safe from harm–the right cleaning products, organic foods, paint with no fumes. But we all have to open the windows, go out the door, breathe in the air. We all want that air to be as clean as possible. And for that, we can’t buy anything (though polluters want to buy the right to pollute.) We have to do something.

That’s why Moms Clean Air Force believes so deeply in what I call Naptime Activism. Because I know how hard it is to find a moment for myself, much less for the whole world. But I also know that the whole world is what awaits my children. And I know that sometimes, being a good mom means being an engaged citizen.

Naptime Activism means you can do things to make the world better, safer, and cleaner – while your child naps. You can sign a petition to Congress faster than you can change a diaper – and right now, you have to get everyone you know to sign our petition against the TRAIN Act. In the blink of an eye you can thank Administrator Lisa Jackson, who is the brave mother of a child afflicted with serious asthma. She’s doing everything she can, not only for her child, but for all of ours. We’ve got to back her up. And yes, it is personal.

Naptime Activism is what an entirely new generation of moms is going to turn to in order to make their voices heard. Because when people in Washington D.C. – or out on the campaign trail – are shouting about abolishing the EPA and killing the Clean Air Act, we have got to shout even louder to tell them to stop those silly games, and get serious about saving lives.

With Naptime Activism, moms can do great good – and there’s even time left over for mom to take a nap. If you haven’t done so, please Join Moms Clean Air Force. And if you have, thanks, and please, twitter this post out to ten friends who should join you.
