Thank you & yea I would definitely make sure im not around with people who smokes...Nobody smokes in my house so I wouldn't worry. I usually onky visit my mothing in law twice a month for the same reason.
It does get in your system and they can tell if its first hand or second hand but depending on your state, a bill was recently passed against so expect visit from staff if any form shows up in the baby, this year they are cracking down on mothers. Just be careful hun, hope nothing goes wrong for you and people start to respect your breathing space.
