Ratoncito Pérez

The story

He wears a small hat and carries a satchel, and he works the rooftops of the Spanish-speaking world by night, going under pillows without ever waking anyone. Where the Tooth Fairy is made of light, Ratoncito Pérez is made of practicality: he is a small working mouse with a job, a route and a tin he goes home to. He is said to be excellent company and a terrible timekeeper.

Where it actually comes from

Ratoncito Pérez has an author and a date, which is rare. The Jesuit priest Luis Coloma wrote him in 1894 for the eight-year-old King Alfonso XIII, who had just lost a tooth — the queen regent asked for a story, and Coloma produced one in which the boy king shrinks to mouse size and tours the poor quarters of Madrid with Pérez, seeing how other children live. The moral was deliberate. A plaque now marks the mouse's address at Calle Arenal 8 in Madrid, and there is a small museum. The tooth-collecting rodent is far older and far wider than the story, though, appearing across Spain, Latin America and France for centuries.

What it does for a child

The mouse works better than the fairy for some children, and it is worth knowing why: he is not magical, he is just small and good at his job. For a child who finds fairies babyish, or who is anxious about a being with powers moving around their bedroom, a mouse with a satchel is far easier to accept. He is also the natural choice for a Spanish-speaking family that wants their own tradition rather than an import.

A little sparkle goes a long way. A pinch of glitter on the windowsill or a crumpled corner makes the letter look delivered, not printed.

Questions parents ask

Who is Ratoncito Pérez?

The tooth-collecting mouse of Spain and most of Latin America, written in 1894 by Father Luis Coloma for the boy king Alfonso XIII. He does the job the Tooth Fairy does in English-speaking countries.

Why a mouse and not a fairy?

Rodent teeth grow continuously, which made mice a natural emblem of strong teeth across Europe long before the winged fairy existed. The mouse is in fact the older and more widespread tradition of the two.

Does Ratoncito Pérez have a real address?

Calle Arenal 8 in Madrid carries a commemorative plaque marking where Coloma placed his home, and there is a small museum there.
