Despite my original comments, and even with the debris issue, I have been fortunate to find the loos a lot cleaner and hardly as a bused as most others who have posted. I've very seldom come across an overly rank loo, though recall those "out of order" signs on them on some of those DEL flights back in the early 90s when AC flew 747s from LHR. I do see this must be one of the less joyous jobs of an FA!
As for the child issue, again highlights why AC should put this minicabin off limits to non-elite or full fare travellers (not that these folks may not have small children and babies, but...) because it appears that check-in and gate agents just love to dump families into the seats that remain open after we elites have had our chance to advance book these "preferred" seats.
