Parents that serve alcohol to a minor are irresponsible and negligent parents. They are harming their children and teaching them bad habits. They think it is cute, harmless and many times funny. They have no clue that the little bit of mashkeh or wine they are giving to the kids only started them off and once they are started they don’t stick to the little bit their parents give them. They continue to help themselves when their parents aren’t looking both at home and elsewhere. And when they get married at the very young age of 21, 22, 23. Their homes are stocked full of the finest wine and liquor even if it costs them big bucks.
And here is the big kicker. They think its funny to give their kids beer, wine and liquor. Its funny isn’t it. I have seen 23-25 year old fathers (idiots) give their 2 and 3 year olds a little beer so they can all sleep Shabbos afternoon. Yup, this happened in the country. I wasn’t the only grandparent that didn’t find this funny at all. I also don’t find it funny when Hatzolah has to be called for a 15 year old with alcohol poisoning. So no, parents do not have a heter to feed their under age kids poison! Their bodies nor their brains are capable of handling it, its against the law for very good reasons.
So here is a bit of unsolicited advice. EVERYONE should be careful about alcohol use. Be careful what kind of role modeling you are displaying for your kids. Remember why we keep wine and liquor around and its purpose for Kidush and not for indulging. Remember that moderation is the key to success and that the law of the land is also important to follow not only the Laws of the Torah. It is very important to behave as Ben Torah and not only to be a Ben Torah.
