Fair enough. There is a reason there are not many successful fiction series featuring a new parent battling sleep deprivation and diapers, though. I honestly think skipping that part is doing US a favor more than anything.
There are plenty of narrative reasons to do it, but there are also plenty of narrative methods to deal with that creatively, without a Sudden Parenthood MOAB. I would've been WAY more on board with Harry's "I MUST PROTECT MY DAUGHTER" attitude in Changes if we had known he'd had a daughter for longer than five pages. I get it, and there are character reasons for Harry to immediately be Papa Bear, but
I wasn't Papa Bear alongside him, if that makes sense. In Changes, Maggie is a MacGuffin, and I tend to prefer it when MacGuffins aren't people.
For instance, when Molly is taken in Proven Guilty, I was worried about her, because I knew who Molly was, and liked her character. If Harry was instead chasing after, say, Sandra Marling, or Boyfriend Nelson, my reaction would be "Meh."
Don't get me wrong, Changes is in my top three, but mostly because of the lunatic pacing. I would've been way more invested in Harry's primary motivation if I had anything to invest in, aside from Harry's desires.
