One more from the “can’t believe I forgot to post it” pile. Might as well now, even though it’s uuuh about two years old. Ooops. And also, yes, I am AWARE I mixed up Discord’s arms. Just assume the lord of chaos just switched around his limbs a little bit.

So, in my continuity, Pinkie Pie is living her best polyamorous life with her husbands Discord and Cheese Sandwich. Though she was together with Discord first and longer and theirs is their firstborn - Eris Discordia Pie (here, being held by Cheese Sandwich).
This picture takes place shortly after Pinkie and Cheese’s first kid, Strawberry Milkshake (here in Discord’s arms), was born.
Discord and Cheese Sandwich get along pretty well and they share their fatherly duties, both loving the other’s kids as much as their own.
(Though Discord/Pinkie only have one biological kid; too much chaos would be born from them both and when Eris turned out to be a draconequus like Discord, they agreed that all future children should perhaps, for the sake of the universe’s safety, be Cheese’s.)

Strawberry Milkshake & Eris Discordia all grown up!
