Flat feet? Tip toes when standing?

Anyone else’s baby? Vi turned 8 months on the 2nd and is very interested in standing, but almost always does it while tip toeing. Ideas on how to encourage her to be flat footed? Her daddy has flat feet and she doesn’t have an arch to her feet. Does this come later? Could it be the reason why she stands on her tip toes? My other friends say their babies never stood on their tip toes until after they learned how to stand and walk. Im going to talk to her pediatrician at her 9 month appointment if I can’t figure it out by then. Pictures for attention and to show off her flat feet, unfortunately you can’t see her tip toeing while standing because her pjs are too long. 😩
