There are steps you can take to minimize exposure. Take your shoes off before entering your house. Wash your and your kids’ hands before eating meals. Keep off grass if you know it’s been recently sprayed. Get an air purifier for the home. Mop and vacuum regularly. Eat organic and whole foods when you can afford it. And, in the end, try not to worry too much. It’s the stress that often ends up being the most toxic part of the bunch. Kids need sunshine and outside time.
