The other night my bedroom (where DS 3.5mo sleeps) smelt strongly of smoke. It was a really warm night and I had to shut the windows. I've now noticed the same again tonight and have just realised my next door neighbour has a chimenea/log burner type thing in their back garden. The smell of smoke is quite strong. Is this unsafe for my little one in any way? I hate sleeping with the window shut but also hate the smell of smoke
