Harry Potter is involved in a potions accident which ends up with him de-aging to a foetus and implanting in the womb of Severus Snape, who is a bearer. Severus can no longer spy, to the chagrin of Albus Dumbledore, but he uses it as an opportunity to show his true self, the person he has been forced to hide for over twenty years.

And maybe, just maybe, he can save his students from the pressures of war.

Mentions of physical, emotional and sexual abuse that various characters are trying to heal from. Many characters being bashed.

With a letter from the head of the Prince family demanding he come to the Christmas celebrations with his child, Severus decides to pass Harry off as his son in favor of not turning the child over to social services or the Ministry due to his lack of a home.

Can this Christmas be a new beginning for both a man regretting his life choices and child who desires to belong to someone? And how will Harry fare among a pureblood family and in a new school out of his comfort zone? Can the Christmas season make miracles themselves happen?
