Claude and byleth gave to make hilda and Leonie godmother because they would fistfight for the right to their children. Lorenz is hoping for another child so he can be god father but byleth really didn't like being pregnant first time around and alois has dibs on a his father position
For my chaos children headcanon, I actually have a little something about this already *clears throat*
Leonie insists she's the aunt and gives Hilda the godmother position because Byleth is "basically her sister" anyway
Hilda Valentine Goneril is the most attentive and doting godmother ever and Alois is the most weepy uncle ever while Lorenz and Seteth are actually the ones who get into glaring matches over who gets to be godfather
Byleth meanwhile tells them to just work it out among themselves, she didn't like being pregnant the first time and the second wasn't any better so a third kid? Hell nah!
Hilda is supremely disappointed she didn't get to be around pregnant Byleth and dote on her too because in my headcanon, Byleth and Claude both establish a democracy in their countries and then disappear on a journey around the world for a few years until they randomly come back with a two toddlers and make Hilda faint on the spot
Ignatz just wants to draw a family portrait pls
