Okay, so Amaranth is the daughter of Twilight and Timber. But, Twilight found out through Sunset that he was cheating on her whilst she was pregnant. But after that she just didn’t trust boys anymore, but, when Twilight gave birth to Amaranth, Sunset, was there to see her child. And at that moment, Twilight realized that she actually liked Sunset more than just a friend, so in the moment, she kissed Sunset, which ended in them becoming an item, with an adorable daughter.

And how Twilight gave birth to Acacia? Simple. She and Sunset simply traveled to the pony world where lesbians can indeed give birth to biological kids. After Twilight was officially pregnant, they headed back to the human world so that Twilight didn’t accidentally give birth to a pony baby instead of a human baby. No, they are not married, and don’t plan on it.
