If you think that your D

is not sweet enough, possibly you are the reason. Maybe you are too sweet, so your hu*****and tends to take care of you a lot. Your D just follows your hu*****and to start to take care of you, at least think about you a lot.

If you want your D to be sweet, you have to be a very caring mother. If you give your D the freedom to be independent, she will be independent and won't be sweet enough. It's just give and take.

It's just my view.
