Smoking around our baby.

I need some advice, my partners family are heavy smokers and I’m super anxious about them smoking around our baby.

I have had many complications and didn’t think I’d ever have my own baby and I feel so overprotective! Is telling his family they can’t hold him if they smoke or smell of smoke horrible on my behalf? I don’t want them to miss out on him but also the thought of someone smoking around him or holding his little hands smelling of smoke freaks me out!

I had BAD asthma as a child from second hand smoke and really don’t want that for my baby.

Am I going mad????
