I'm not sure where to post this one

Chef Cara • Currently cook for a fine dining restaurant in Traverse City. Single, 29, chef, would love to be a mom someday.
But do you ladies know how to get a smell out of a carpet? I had my niece and nephew over last weekend and my niece went to sleep and pooped in her pull-up and it overflowed onto the floor. I've tried soap and water, Resolve, 409 and baking soda. I'm still smelling it and I've cleaned it everyday since they left pretty much. Help please!
