Arthas probably was inappropriately chucked into the Maw given a pretty naughty Kyrian told Maw-tainted Uther to do it, and Uther didn't really even question it, just came up with an easy rationale for his choice, and if he was chucked in there inappropriately, it certainly raises the question of how many others have been.
But I'm not aware of any random kids chucked into the Maw.
