Francisco "Fran" Rivera Ordóñez was in the hospital recovering from a serious goring when his wife gave birth to his daughter Carmen on August 19th.
On Sunday night he posted the photograph of a training session in which he clutched his baby daughter in his arms while practicing cape work with a bull calf.
"Carmen's debut," he wrote under the hashtag #orgullodesangre - meaning proud of blood in English.
"This is the fifth generation of bullfighters in our family. My grandfather used to bullfight with me and my father like this. My father also used to bullfight like this with me, and I have done it with my daughter Cayetana and now Carmen."
Perhaps to illustrate that such a practice was in keeping with the family tradition, he posted a photograph of himself as a toddler atop the shoulders of his father.
Alongside messages of support from his fans, the torero received criticism for putting his daughter in unnecessary danger.

"I am anti-bullfgihting, but I think that Fran Rivera has crossed the line, just for putting his daughter in danger," wrote one.
Rivera Ordóñez - known to Spaniards as "Fran" - is one of the nation's most popular bullfighter and regularly appears in the pages of gossip magazines.
Rivera Ordóñez's father, the great bullfighter Paquirri, was gored to death during a bullfight in Pozoblanco, Córdoba, in 1984, aged just 36.
