The first child and eldest son of Albrecht V, Duke of Austria (future King of the Romans) and Eliska of Luxemburg (daughter of Holy Roman Emperor Sigmund, King of Hungary and Bohemia) was born in 1431. He died in 1435. Hopefully he'd be healthier than his OTL brother was (Ladislaus the Posthumous had leukaemia), but assuming that his parents still die roughly on schedule, dealing with an 8 year old child is a very different kettle of fish to an unborn baby (who may or may not be of the wrong gender).
What might change? And what might remain more or less the same?
