Today I was taking DS into swimming and we walked past a man smoking outside the swimming place (idiot I know!) and DS was very curious as to what the man was doing. He kept staring and asked me what's that man eating? I didn't know what to say, I was a little stumped so changed the subject. Dp and I don't smoke, a few family members and friends do but generally not in view of DS. I'm curious as to how people explain smoking to their kids? DS is only 2.5 and I just don't know how to say it to him? Do I just say yukky? What have you said to your toddlers/young children explaining smoking?
