With DD1, I waited 7 months to get first information about her, and then we started introductions nearly 4 months later. DD2, got initial information about her 10 months after approval, we agreed a match about 3 months after that, and started intros about 2 months after that
Although, during those 7 and 10 months, I had other potential matches and visits, so it could have been quicker. I'm glad it wasn't, because I now have them, but I was seeing profiles quickly after approval
(recieving initial info) I've known people wait a couple of days, or 2 years. However long it takes, have faith the right child will come to you in the end
I would say this - when you have information, which looks positive and you want to go forwards, get as much information as possible. Don't proceed without lots of information, even though it's horrid waiting. Don't let a match get rushed
