Dp's friend and his wife have just had a little boy who's now 4 weeks old. I don't know them very well and don't want to preach or anything like that. But the thing is, the wife smokes about 10 cigarettes a day and is breastfeeding. I've been trying to find out some information about what the risks are about it so that in some way I could perhaps hint to them that it's not a good idea but I can't find anything conclusive. There's loads on drinking alcohol but nothing on smoking. She says that the benefits of breastfeeding outweigh the risks of her smoking but I'm not so sure. Does anyone know anything about this subject?
