Theres no one on this entire planet that hasnt thought of the possibility of a Time Lord baby, especially after the close-to-realistic Tumblr images that surfaced the internet for months and drove Whovians into interminable excitement.

It is very hard to tell what kind of a father the meta-crisis Tenth Doctor would be, judging by his raunchy and swift personality, but its quite evident that when he and Rose are together, everything starts to come together and resolve on its own. Once again, its safe to assume that the event takes place after their marriage and the boy grows up to take to his father in valor and mother in combat.
