I absolutely won’t be understanding of anything a parent intentionally does, knowing that it has the potential to harm their child, born or unborn.
My mum smoked whilst pregnant with me, liked to claim that it was a different time then and you didn’t know the dangers. Plausible, if not for the fact I was born in the 80’s, not the 60’s. Love my mum dearly, but I will and do judge her choice to smoke whilst pregnant.
i would also say that if a woman is in the grips of an addiction, it’s possibly not the right time to get pregnant and have children, no?
