Twilight's mother is the mother that respects your decisions in life and can be proud of them.

Pinkie's mother is the mother that may not always agree with your choices but can respect it if you're fully convinced it's doing the right thing.

Rainbow's mother is the mom that supports you throughout a great expansion of your life. She's the supportive mother.

Applejack's mom is the loving and sweet mom that will always think the best for her family over probably even herself if possibly.



Rarity's mother, although not enough screen time for her but she seems to the kind of mother to help their child or children even if they don't ask for it.

Fluttershy's mother is the comprehensive and kind mother that will sacrifice certain things for her child and we'll gladly have her child be a burdan for a while if it means it can help her child.



For me those are the kinds of mother/mother traits the mom 6 have.
