Re-watching Dragon Ball Z I have noticed that Chi-Chi's main goal in DBZ was to stop Gohan from training and force him to study instead. But once the Cell arc finishes and Goten is born. Chi-Chi doesn't treat him the same way.
It blew my mind that she even let him train at all but apparently through training with her Goten was able to transform into a super saiyan.
My question is why? Is it because Goku officially passed on so her character developed a bit? I never actually actuallly thought about it until now.
