In the first book, Harry did nearly swallow the snitch. I believe it was the Slytherin captain who said something like it, "He didn't catch it, he nearly swallowed it!". And in my opinion, mid-twenties isn't early at all for having kids, but it's a personal decision. Hermione is no less "brilliant" for having children in her mid-twenties, either. At all. I was surprised they didn't have kids way younger than that, like most books have it, so it was a bit different than usual. The book was my favorite out the whole series, but, to each their own.
