question: My daughter visits her father on the weekends and Ive noticed that everytime she comes back from her visit, she is sick. Most of the time its strep. She had strep at least 6-8times in 2011. My daughter recently told me that her dad smokes in the house around her and her brother all the time. My question is can second hand smoke have something to do with her coming home sick every single time she goes over there?
