We have strep throat and scarlet fever at my house. Again. Six of the seven kids are on antibiotics.
Here's a tip if you don't want strep running through your whole house. Make sure your 5-year old doesn't get into the fridge and drink milk straight from the carton. Not that my five-year old would ever do such a thing. Nope.
Oh, and another tip if you don't want your kid's friends getting strep. Make sure your teens don't share their Mountain Dew fountain drink with one straw with their friends. Just so you know, you can tell them not to do such things for 15 years and they still do it!
