Regarding "brewing with a minor," note that it is legal in every state for a parent/guardian to serve their child alcohol inside their own home.
e.g. At holiday/family dinnertime, junior gets a taste of the toasting beverage of choice
Since you're next door, that's not exactly inside the home but given that the parent(s?) consent, I don't forsee any problems. Besides, since he's under your supervision and not directly consuming the beverage in question, I'd say it's no different than if you were teaching him how to cook with alcohol - say, duck a l'orange. Furthermore, if he's just helping you make wort (which isn't beer - yet), I don't see how any law regarding alcoholic beverages applies at all. At the very least, make sure that you are the one who pitches the yeast. That way, the only thing your "assistant" has ever done is make glorified sugar-water.
I don't agree with restrictions on alcoholic beverages. It's been an integral and essential part of human civilization for the entirety of recorded history and I don't understand how in the last 50 years we can suddenly decide that you shouldn't drink unless you're 21. There's no social, behavioral, psychological or medical reason for that (or any) such restriction.
Don't get me wrong, there is certainly compelling evidence that one shouldn't
abuse alcohol and certainly responsible consumption
rates vary with body weight (ergo, in growing children, age) but still, there's no reason to bar consumption completely.
Again, children should be allowed to partake in the Thanksgiving Day toast, consumption at religious ceremonies, etc. and the law makes this provision but still, considering that many children in modern culture leave the home upon graduating high school (appx. 18 years of age), it's silly to legally extend parental supervision requirements to those people who are, for most respects, otherwise independent.
Sadly, the neo-prohibitionists (such as the usurpers of modern-day MADD) don't see it this way and continue to misinform public opinion regarding a substance that is still to this day highly valuable to human life.
I say, all the more reason to bring the next generation up right!
