A friend who smokes came round today, he didn’t smoke in the house but could strongly smell cigarettes on him and he probably had one before he came into the house. I let him hold my baby for a while, and didn’t really think about it until afterwards but now I’m worried my baby will have been affected by this and am worried about sids. Do you think it’s ok and if not is there anything I can do? Aibu to be worried about this?
