Rhaenyra's three eldest sons all died fighting during the Dance of the Dragons, but her two youngest sons, the sons by her second husband, Prince Daemon, survived the civil war.
The comes the final blow: Rhaenyra's baby daughter – whom they'd named Visenya, according to George R.R. Martin's Fire and Blood – is stillborn after a brutal, bloody labor. This is similar to the book, where the baby also has dragon-like birth defects, including a hole in her chest and a small tail.
Aegon III, aka Aegon the Younger: Rhaenyra and Daemon's first child together.
However, Daemon and Rhaenyra's next two children do survive to adulthood — their second eldest child Aegon III, and their third child Viserys II.
Visenya Targaryen
According to the fool Mushroom, Visenya came out malformed with defects that resembled dragons more than men (although this is an unconfirmed account.) Princess Rhaenyra and Prince Daemon's only daughter was stillborn.

Prosthetic designer confirms: the baby was deformed
“When the babe at last came forth, she proved indeed a monster: a stillborn girl, twisted and malformed, with a hole in her chest where her heart should have been and a stubby, scaled tail. The dead girl had been named Visenya.
In 117 AC, Rhaenyra gave birth to her third son, whom Laenor named Joffrey, in honor of Ser Joffrey Lonmouth.
Since Daemon's body was never recovered from the Gods Eye, singers say that he lived to spend the rest of his days in secret with Nettles. Daemon never achieved his ambition to sit on the Iron Throne, though his sons Aegon III and Viserys II eventually did.
When finally did give birth to the baby, it is said that the child had a hole where her heart should have been, a tail, and scales for skin—a monster, as her mother had cursed her to be.
Rhaenyra and Daemon's sons Aegon, Viserys, and Visenya Targaryen. Sorry for the spoiler, but we did watch Daemon and Rhaenyra get married in last week's episode, so you probably knew this was coming! We haven't seen them yet in the show, but Daemon and Rhaenyra have three sons together.
Her next child whom she's now pregnant with, however, will be a different story. In House of the Dragon episode 8, Rhaenyra Targaryen is pregnant with her daughter Visenya. Despite Rhaenyra and Daemon's excitement over having another child, their daughter will tragically never take a breath of air.
The episode doesn't really beat around the bush when revealing that Harwin Strong (Ryan Corr) is the father of Rhaenyra's children. He's there soon after baby Joffrey is born so he can meet him, and later on in the episode Jacaerys (Leo Hart) even asks his mom if Harwin is his real dad.
The shock of the loss of her father, combined with the Greens' ruthless betrayal sends her into early labor. Without modern medicine, a baby born so early had very little chance of survival in the best of circumstances - and in these terrible conditions the baby, a girl named Visenya, is stillborn.
Daemon is said to love his family by both the showrunners and fans but we're only shown his love for Viserys and Rhaenyra. Even Matt Smith has said that they're the only people Daemon cares about. Going by the actor's words and what we've seen on the show, Daemon doesn't seem to care about his daughters.
He died during the Storming of the Dragonpit trying to ride Syrax, his mother's dragon, in order to save the dragons in the Dragonpit, but the dragon rejected him and he crashed to the ground, dying instantly.
But the death of Rhaenyra's son Lucerys at the hands of Aegon's brother Aemond—mistake or not—enraged Rhaenyra and kicked off a civil war that will play out over several seasons.
Aegon II died not long after Rhaenyra, and Aegon inherited the throne as Aegon III. Since Aegon II's two sons and two brothers died during the war, he married his cousin Jaehaera to reconcile both factions.
That's right, during the Oct. 2 episode of House of the Dragon, Rhaenyra (Emma D'Arcy) and Daemon (Matt Smith) stopped fighting their feelings for one another and finally got together. However, this was more than just an illicit liaison, as Rhaenyra and Daemon got married at the end of the episode.
It isn't explicitly stated in the show, but because we learn after episode six that all three boys have dark brown hair — and despite Rhaenyra and Laenor's matching blond color — it has been strongly implied that they are actually the children of Ser Harwin Strong, the Lord Commander of the City Watch.
Across the course of the first season, Rhaenyra gave birth to six children. All of her children were boys except the last pregnancy -- which ended in heart-rending tragedy.
Like Laenor Velaryon's sexuality, it was a “known secret” in the Red Keep that Harwin Strong was the father to Rhaenyra's three children: Jacaerys, Lucerys, and Joffrey.
In the book, Visenya was described as being born with dragon-like defects, including scales, a tail, and a twisted body. Rhaenyra's baby did end up having scale-like defects and a malformed body in House of the Dragon, which aligns with the occasional reports of Targaryen women bearing dragon-like stillborn children.
Rhaenyra's baby died during childbirth.
Unfortunately, Visenya was born a month early — Rhaenyra's labour was brought on by the news that Aegon II Targaryen had stolen the throne from her — and was stillborn.
One of the first times we see Rhaenyra as truly angry throughout the entirety of Season 1 is during the traumatic miscarriage of her daughter Visenya.
