Some time before Avengers Disassembled, Wanda went to Doom to ask for more power to bring back her kids, Wiccan and Speed.
Then AD, Wanda Dissassembled Avengers. Then Hawkeye reappeared before Avengers Finale.
Then HoM, Wanda disassembled mutants and herself, ending up in Wandagore.
Before Civil War, Hawkeye visited Dr Strange and then Clint visited Wanda in Wandagore, and left.
During the whole Initiative, SI, DR, Doom and Wanda kept up contact and got engaged? Not sure.
Then we see Doom dissect Gods, Doom attack Wakanda, and finally, Doom lose his memory in World War Hulks. Wanda certainly would have nothing to do with Doom during this cycle.
So Doom is now stupid during the Heroic Age.
Now comes Fear Itself and Reed Richards gives Doom back his mojo.
Maybe here, during FI, Doom and Wanda get engaged?
After FI, Wiccan decides to visit Wanda and finds she's an amnesiac and engaged to Doom? Doom and Wanda try to power Wanda up again, and Doom takes all the power, and dumps Wanda.
Somewhere in all this, the FF ask Doom to hold off the Celestials and Doom is sent to the Council of Reeds to collect the Infinity Gauntlet. Doom is now permanently out of the picture.
Wanda gets her memory back, tried to help the mutants, tries to join the Avengers, and ends up in the West Coast compound alone.
I don't know that Childrens Crusade happens after FI. All we know is Wiccan recalls incidents happening after FI. Maybe Childrens Crusade happened before Doom started operating on Gods? Just after Doom is released from jail by Osborn in Dark Reign, and before the Gods are invited to live in Latveria? It would explain Dooms self destruction up to WWH's.
