I'm not entirely sure why it would be such a good idea to make what the parents did in this case a felony, as it appears Illinois is poised to do. The parents are, I'm sure, already facing some potentially catastrophic financial consequences of this action -- making them felons just compounds the financial and familial problems without providing any kind of solution.
That said, if the parents broke the law then they should be punished. If the law is too harsh or too lenient, then that's an argument to change the law.

But prohibiting drinking alcohol privately is state's affair.
Well, not exactly. Congress couldn't change the drinking age laws, because those are under the exclusive jurisdiction of the states. What the National Minimum Drinking Age Act did was coerce the states into changing their drinking age laws by threatening to withhold federal highway funds from the states if they didn't. So much for Ronald Reagan's "new federalism."
