The stuff with her kid's bedroom seems like it's real, it's weird to include it otherwise, so she might have lost a child at some point in her past.
BUT all jokes aside, the kid's name was Nicholas Scratch. Ol' Scratch is a nickname for the devil so...Mephisto?
But Google also tells me there's just a Marvel supervillain named Nicholas Scratch who's had dealings with Agatha so it's probably something like that lol.
I thought that it was also a reference to
her rabbit who is named Senor Scratchy https://marvelcinematicuniverse.fandom.com/wiki/Se%C3%B1or_Scratchy
