I'm fed up with hearing this as an excuse for continuing to smoke in pregnancy! I've heard people say this in real life, on TV, and now Stacey Solomon is claiming her doctor OK'd her smoking too.
Yes, quitting smoking is hard, but don't claim it's better for your baby to be exposed to carbon monoxide, cyanide and nicotine fgs.
I would have a lot more sympathy if they said "I know it's awful and I'm trying my hardest to stop but I'm struggling and have slipped up"
