Greetings, Joe.
Have you ever had kids????
You make it sound like it is more trouble than it is worth and a real problem for anyone within 10 miles. Get off it. I will take a baby or little kid over some of the slobs that come into the park all the time and make a racket and leave a mess expecting everyone else to pick up after them or just ignore them. Those people are the ones that should stay home not an 11 month old kid. I am sure that the parents are more than responsible, given the amount of effort that they have already put into research and thinking about bringing a little kid into the park.

It was one of the best things that I did for my kids, introducing them to canoeing at an early age, ( 4 months was my youngest ), they are all adults now, and love the wilderness. We never left any mess in a camp.
I carried a "diaper pack" for 2 weeks that weighed 65 lbs at the end of the trip, and I would do it again in a heart beat. Our kids never got sun burn once, there are plenty of good hats and other clothes to cover them up and protect them. At that age they still sleep a lot. Do you really think that a little kid can have that much trouble in a canoe? If so you haven't been around little kids much. IMHO they are easier to take care of in the woods than at home. So much more for them to be interested in that is good for them than the crap at home in the city.
Yes it is a lot of work taking a young child to Quetico, but when is it not a lot of work raising kids? The kid will be fine and no one will be "disturbed" by him.
Sorry for the rant, but where are we going to get paddlers from if we don't get our kids involved? At least then we can teach them good wilderness etiquette and hopefully they won't turn into canoe slobs that are a "real" problem.
