Going back to the boxing gym

When things calmed down a bit, Sena's parents had me sit down in front of them to be interrogated, they asked the usual questions and I answered them without faltering. Moreover, with Sena sticking to my side, they couldn't grill me too much or their daughter would pout at them.

Her mother was the first to crack a smile.

"Okay, if she's happy with you, then we're happy too. But remember, we're expecting grandkids before marriage!" She joked, but there was a hint of seriousness in her tone.

"Honey, what are you saying?!" Sena's father reacted almost comically, causing both mother and daughter to laugh.

"Dad, don't you want to carry your grandchild while watching my match?"

This girl. What kind of picture was she trying to paint here?

"That's not... bad. But that will be dangerous for you! How can you be on top form if you went back to the ring after giving birth!"

And now, even her father was taking her words at face value. What should I say in this situation?
