Concerns with family smokers & my infant while on vacation

First I am a non smoker. My answer is Yes and NO. There has been studys done that has proven that smoking around infants and toddlers can develop the said above problems, BUT and here is the big BUT for the longest time in the USA smoking was Everywhere. Restaurants, planes, HOSPITALS you name it. Im not saying smoking isint bad, it is absolutely terrible. But if being around the smoke would have to be prolonged. Hope this helps
