I know this is a post and run but TS's post reminded me of the immense wisdom on this forum. I have a similar conundrum. My parents offered to care for my baby for a few months but dad is a chain smoker. He smokes outside but still reeks of smoke. I am reluctant to have him around a newborn after reading about third-hand smoke. He will not discuss this issue with me but he wants to come visit. My mother and the rest of the family think I am being unreasonable because of my stance. What would you do?
