i agree with all you girls.
i am an ex smoker myself (so i am terrible to smokers!!! us ex smokers always are!)
anyway Richards nan lives with his aunt & uncle, but because they chain smoke the Nan has never seen Louie, its a shame coz shes 80 something & too frail to come here & see him, buy coz i know his aunt & uncle would never stop just while i am there with Louie, than they've never even seen him.
they would think i was mad if i ever said anything, so i just don't go round there.
have a word with your friend & just explain the importance of not smoking around babies/children, also mention the link with cot death, this might scare her into realising.
