New parenting question!!

Brittany

My first baby has not been born yet. She is due April 14th! 💕But I have a question as this is our first child and I've been stressing about this.... on my boyfriends side of the family a lot of people smoke cigarettes. 🚬Do we need to ask them to change & wash their hands every time before they hold our baby? How can I tell them to do so without sounding bitchy?? 🚭
