To be fair, Moffat has been building this particular element of The Doctor's history since the show returned. Madame de Pompadour exclaimed, following her mind-link with The Tenth Doctor, "Such a lonely little boy...." and I'm certain there are other references scattered around his work. Besides, I like the idea that a lonely, crying little boy grew up to fight monsters and save the universe. That's a nice message for the children watching.
