Early builds of Fable 2 supposedly had pregnant playable woman before being replaced by a cutscene saying you had a baby and then showing a baby cradle being present in your home.
"Originally we did plan to depict pregnancy in game with the female hero's stomach expanding," Peter Molyneux said. Lionhead Studios decided to opt for a cut scene instead, though, after considering all the moral quandaries that come of having a six-month pregnant mom-to-be wielding a broadsword and getting cut up by bandits.
Also planned was if your hero died, your child would replace you, this was also removed because playtesters had as many kids as they could have to serve as extra lives.

More of a child creating feature. In Awakening no female character actually gets pregnant in the game's story timeframe (the idea seems to be they have a kid after the story ends). Male/female couples that get a highest support rank get married and than a 20 year "child" (with a combo of their parent stats/skills) who time travels from the post apocalyptic future can be recruited in their newly unlocked level in the present day.
The only female characters who technically would have been pregnant are in a "time skip" portion of the story would be the 5-6 female characters who serve as Chrom's wife/mother of Lucina).
Haven't played Fates but I think it does the same support rank for couples but your resulting baby is then thrown into a dimension where time goes faster allowing you to get a 20 year old child unit without anything like time travel being involved in the story (yeah, it sounds stupid and kinda fucked up when you think about it).
While Geneology of the Holy War take place over two generations, parents characters in the first half and then a second generation story (timespan wise like 2 decades later) consisting of whatever children created from the couples of the first generation.
