we're currently staying for 2 weeks at bil/sil's with 8 week old ds. bil smokes. He only smokes outside in the garden, and if we're there too he'll move away or at the very least make sure the smoke is all blowing in the opposite direction. Is that enough though, or is ds still at risk? (occasionally I do get a whiff of it despite his precautions) We can't really ask him not to smoke even in the garden, but should I take ds and go inside when he smokes?
