About our child-friendly Ruby and the Tooth Guardian story
Ruby and the Tooth Guardian is a warm story about meeting a first wobbly tooth with curiosity, questions, and support. Ruby's imagined guardian helps her organise a practical kit, but Ruby remains the person who speaks up, chooses useful help, and decides how to remember the day.
Designed for ages 5-7 around a familiar childhood milestone, the story uses a three-part preparation plan, a trusted adult's calm support, and a child-led choice after the tooth falls out naturally. Versions adapted for other age ranges may differ and may not be equally suitable.
Growing Up · Designed for ages 0-4, ages 5-7, and ages 8-11 · Ruby and Elena can be personalised · Themes include First lost tooth, Supported independence, and Asking for help

Ruby and the Tooth Guardian characters
Meet the original cast of Ruby and the Tooth Guardian and discover which roles are best suited to personalisation—and why.

Ruby
Ideal for personalisationThe child protagonist who notices mixed feelings about her first wobbly tooth, prepares a small support kit, asks for the help she needs, and chooses how to mark the milestone.
Why: Ruby is the child protagonist and viewpoint character in every major beat, so a child can naturally and positively take her place throughout the milestone story.
Tooth Guardian
Cannot be personalisedRuby's friendly imagined companion, who helps her organise questions and rehearse a support plan without touching the tooth, making choices for Ruby, or removing uncertainty.
Why: The character's specific identity as an imagined Tooth Guardian and tooth-milestone guide is essential to the story's imaginative structure, so a customer character cannot naturally replace the role.
Elena
Can be personalisedThe trusted caregiver who listens to Ruby's questions, offers practical help and bounded choices, and stays close while leaving the central action to Ruby.
Why: Elena is a warm, non-shaming caregiver who supports several major beats without taking over, so a trusted adult can naturally and positively fill this recurring role, although it is less central than Ruby's role.
