MIL is a heavy smoker


My MIL invited us to her house for Easter and I have a 2 month old baby that I will be bringing with me but I’m not sure if it’s going to be a good idea since my MIL has been smoking in her house for years and her house now smells like cigarettes as soon as you walk in. She will not be smoking when we’re there but idk if since it has been smoked in it will affect my baby.
