The thing about boundaries is they have to have a consequence. If they aren’t gonna follow your rules, don’t allow them to hold the baby.
Definitely not a small thing, I’m very sensitive to smoke and the smell of it, so I wouldn’t want it around my baby either.
I think it’s a very valid thing, and definitely not small. I think I’ve been so chill with everything when it’s come to my baby, but this is the only one rule I do have. If someone smokes and then want to hold baby they have to change top/take jacket off, spray and wait atleast 15 mins. Second hand smoke lingers for ages and it’s really harmful!
