None that I know of, but I am sure there would be a market for this... at the very least, on routes which are flown multiple times per day then it should be possible to designate some of the flights as "min age 12" or something.
I must admit I was mightily pissed off recently to be in First on a BA from LHR to EWR where there was a baby screaming for at least 30% of the flight. After a while I went and sat in business, which really isn't what I was paying for. The crew were most apologetic and trying hard to help the mother shut the thing up (harder than the mother was trying, frankly). They also gave me the rest of a very nice bottle of wine which I had had one glass from for me to have the rest with my dinner, but there isn't a lot more they can do.
