Cigarette smoke

My sister and my mother both smoke my sister has a four-month-old son and I have a 1 year old daughter. When they come over to visit they reek like cigarette smoke they both smoke a lot so I kindly ask my sister before she came over to either not smoke before she comes or I will give her a shirt to change into. She did change her shirt but had an attitude the whole time because she thinks it's ridiculous that I'm so worried about third hand smoke around my baby. I also used to smoke but I stopped when I was pregnant because I didn't want to hurt my child she smoked her whole pregnancy. She's also kind of anti-vax so she thinks it's ridiculous that I'm so weird about cigarette smell but I vaccinate my baby. Am I wrong for not wanting them to hold my baby when smelling like cigarette smoke? My mom is also being rude to me about it.
