It's hard to be a good mom to your daughter because the mother you needed might not be the mother your daughter needs.
Fiorella had a very good mother, but she was a different person than Fio and the fit wasn't as good as it could have been so Fio resolved to be an even better mother to her daughter. What she didn't realize, when that time came, was that she was trying to mother her daughter as she thought she should have been mothered, but her daughter was a different person than she was.
And if Daughter has children, she'll probably have to deal with one like Fiorella. God help her.
