In the second gen, when the concept was introduced, it was completely pointless since the daycare was RIGHT NEXT TO THE GRASS YOU FIND DITTO IN. In the third gen, in FR/LG, you had to wait until the postgame to use the real daycare anyway. In Emerald, Ditto is not found until postgame. In the 4th gen, Ditto is again not available until postgame no matter what. (unless in HG/SS, which still has it right next to the daycar) And again in the fifth gen until you can reach it during the main plot in BW2. The Daycare itself will not be accessible until postgame, though. (I think) In the sixth gen, Ditto is not made available until just before the 8th gym. In Sun and Moon, you'll just have to wait until you get to the next island.
For a while, they seemed dead set on you not using Ditto until postgame. However, that's fine as no one does breeding until postgame anyway.
