I know a family whose children had (maybe still have) whooping cough. It started sometime around the beginning of July. She told me they are no longer contagious, and seem fine for the most part-- although when they get hot or run around a lot, a couple of them still cough. So, my kids played with their kids yesterday, and I'm freaking out a little. My youngest child is right at 1 year old, which is supposed to be past the "danger" zone but it's still scary!
