I guess Bulma just wants a happy kid.
I mean, she is rich, she is intelligent, her husband and her best friend are the strongest creatures she ever has seen, besides Beerus, which is also a friend, or at least addicted to her (cause of Food). I guess she is happy when her kid is happy, thats it. While Chichi has some strange ideas about pushing intelligence, when his Talent is obviously something completely else.
