I agree with your sentiment - the 'babies' thing with classic cartoons has been done to death (at one point I used to joke with my family about the possibility of a Ghostbuster Babies cartoon), but I don't think Tiny Toons is a good example. For one thing, the Tiny Toon characters are not that young - adolescents or a bit older. But more importantly, they're characters in their own right, with distinct personalities from the older Looney Toon characters, unlike a "babies" cartoon where they're just younger versions of their older selves.
