Not really in my culture but still necessary sometimes I had to step in when my sister's post-natal drinking became too much. Everyone else turned a blind eye, but I couldn't stop thinking about my nephew and an emergency situation. In a mini intervention, we snapped her out of it by saying you can't drive your baby to hospital in an emergency after 2-4 big glasses of wine (she was often on her own in the evenings); and if you did, child protective services would come down on you like hellfire. Plus a bit of "well prove us wrong that you don't need it to relax" etc. It worked, quickly, luckily
