but the fact that " Parents giving gin or cognac to their toddlers are just bad parents, a case for CPS, end of discussion" seems so absolutely self-evident to you has been brought about by a century of regulations, public education and resulting stigma/taboo. believe it or not, but giving (small amounts) of alcohol to toddlers and even infants (by way of drinking a shot before breastfeeding) was actually a shockingly widespread practice across many countries over 100 years ago. it took real effort by governments to get people to stop doing that and get us to a point where we are now - where such behaviour is self-evidently bad to anyone in their right mind and we've collectively agreed that it's in everyone's best interest that the state takes children of parents who do this to them into custody. it is not unthinkable that future generations, perhaps not even that far into the future will regard and regulate tablet/phone/[smart device] usage by toddlers in the exact same way.

I believe that in marketing something to children, you become co-responsible for the usage situation you are promoting, even as parents share that responsibility. Marketing cigarettes, gin or tablets to children would be immoral in deeper ways than doing the same to adults. I stand by that.

For the record I think the gin industry should in fact be regulated from marketing their product as a pacificer for kids. I find it very difficult to believe that you don't.
