Would you allow your child to be pushed in a pram by somebody smoking a cigarette? Not in a confined place, very much a public area, but nonetheless pushing your child in a pram smoking?
Yes or No.
Personally, if I can avoid this happening then I do. I do not smoke and don't allow my baby to be pushed by anyone smoking, whether it's a grandparent or friend it's a big no no for me.
Am I being too precious?
