Behind the scenes
Staff writer Bryan Cogman came up with the idea of the stillborn fetuses being preserved in jars. Cogman said in an interview, "It was a proud day for me as a writer when I walked on set and saw those magnificently nasty prop dead babies floating in those jars."[1]
In the books
In the A Song of Ice and Fire book series, there is no mention Selyse Baratheon having any stillborn sons.
