CLINICAL UNDERSTANDING
A little friend.
A question worth exploring.
Can a familiar companion, shared stories and playful participation make medicine time easier for children and their grown-ups?
That is the question behind Tailsiee. Here is the research informing our approach, how it relates to the product, and where the evidence stops.
Tailsiee is in development. We have not yet established that it reduces medicine refusal, improves adherence or reduces distress. The studies below evaluate other approaches in other settings; none tests Tailsiee.
01 / UNDERSTANDING THE MOMENT
There is more behind a “no”.
Medicine-taking can involve taste, texture, fear, discomfort and a child’s need for some control. Calling every refusal a tantrum can miss what is making the moment hard. A story cannot make a bitter medicine taste different or resolve a swallowing difficulty.
Adherence means following the agreed medicine instructions: the right amount, at the right times, for the intended duration. A child’s willingness is one part of that. Caregiver understanding, accurate measurement and the practical demands of family life matter too. The caregiver counselling study below illustrates this distinction.
Our starting point is medicine time during short illnesses, including prescribed antibiotic courses. Scheduled treatment and medicine given only when needed require different routines. We do not turn either into a daily streak or a reason to give an extra dose.
02 / OUR WORKING THESIS
Familiarity. Connection.
A small part to play.
Our hypothesis is that these three elements could support a child’s willingness to participate in medicine time. Whether that translates into better adherence needs direct testing.
A recurring companion
The character on the carrier also appears in the stories and playkit. We are exploring whether recognising the same friend can make the experience feel more familiar.
A shared story
A character with feelings gives a child and grown-up something to talk about. The story makes room for questions, hesitation and comfort.
Meaningful participation
Choosing a scene or moving a puppet offers a small, appropriate choice. A grown-up continues to manage all medicine decisions and administration.
What we mean by gamification
We mean using characters, small choices and a continuing story to invite participation. Progress belongs to the story. A child does not earn a friend’s affection by swallowing medicine, lose access to play for refusing, or need a dose to unlock the next chapter.
A child should be able to keep enjoying Pip and Tiggy after treatment ends. A story’s ending does not set a recovery deadline or determine how long medicine should be taken.
03 / READING THE EVIDENCE
What research can tell us.
And what it cannot.
This is a selected evidence overview, not a systematic review. We distinguish clinical guidance, research syntheses and trials. Institutional affiliations identify the researchers; they do not imply a partnership with, or endorsement of, Tailsiee.
Clinical report · 2018, reaffirmed 2025
The Power of Play
What the source found or recommends
This clinical report brings together research on play and child development. It describes benefits of developmentally appropriate play with parents and peers for relationships, social-emotional skills and self-regulation.
What that means for Tailsiee
It supports making shared play part of the design. It is a research synthesis, not a trial of medicine-taking or of Tailsiee. The lead author’s Harvard affiliation is not a Harvard endorsement of this product.

Randomised study · 2021
Storytelling during hospital care
What the source found or recommends
Brockington and colleagues randomly assigned 81 children in intensive care to a live storytelling session or a riddle activity. After the session, the storytelling group showed greater reductions in pain scores and cortisol, alongside increased oxytocin. The children were around seven years old on average.
What that means for Tailsiee
It offers a reason to study stories in care settings. A live hospital session is different from an audio story at home. The study did not measure refused doses, antibiotic-course adherence or lasting effects.

Practical guidance · Not a trial
Helping young children take medicine
What the source found or recommends
This caregiver resource suggests age-appropriate explanations, preparation, play and limited choices as ways to support young children during medicine-taking.
What that means for Tailsiee
It informs how an adult could introduce the experience and offer choices about the story or play. It is clinical guidance, not evidence that a carrier or playkit improves adherence. The medicine, dose and timing stay with the child’s care instructions.

Randomised feasibility study · 2019
A companion in a hospital setting
What the source found or recommends
Logan and colleagues randomised 54 hospitalised children aged 3–10 to an interactive robot bear, a tablet avatar or a plush bear with human presence. Children in the robot group reported more positive affect than those with the plush bear. Researchers included teams at Boston Children’s Hospital, MIT and Harvard Medical School.
What that means for Tailsiee
An interactive social robot differs substantially from a passive character carrier. This small study concerns feasibility and emotional experience in hospital, not home medicine-taking or adherence. It cannot establish that Pip or Tiggy produces the same effect.

Randomised trial · 2008
Can a game influence adherence?
What the source found or recommends
The Re-Mission trial enrolled 375 people aged 13–29 receiving cancer treatment. A purpose-built video game improved objectively measured adherence to prophylactic antibiotics and oral chemotherapy in the subsets assessed. Self-reported adherence, stress and quality of life did not improve.
What that means for Tailsiee
This is a useful precedent for testing a specific game against a specific treatment behaviour. The participants, illness, medicine format and game are very different from young children taking syrup during a short illness. Its results cannot be transferred to Tailsiee.

Randomised trial · 2008
The grown-up’s instructions matter too
What the source found or recommends
Yin and colleagues tested pictogram-based counselling with caregivers of young children prescribed liquid medicines. The intervention reduced observed dosing errors and improved reported adherence in the relevant follow-up group.
What that means for Tailsiee
Child willingness is only one part of adherence. Clear instructions and accurate measurement also matter. This trial tested caregiver counselling, not play, and does not establish a benefit from a character carrier.

Systematic review · 2026 · Abstract reviewed
Picture books and food exploration
What the source found or recommends
Burnett and colleagues reviewed 16 studies of picture books and vegetable intake, liking or willingness to taste in children aged 18 months to six years. The abstract reports benefits in several studies and calls for larger samples and follow-up.
What that means for Tailsiee
This informs our planned food-exploration activities. Picture books differ from recorded audio, and the review does not test Tailsiee. This summary is based on the abstract; we have not assessed the full report or assigned an overall certainty rating.

04 / WHAT WE STILL NEED TO LEARN
A good idea needs
its own evidence.
These are proposed evaluation questions, not results or an announcement of an ongoing clinical trial.
- Will children and parents use it?Understand age suitability, interest, effort and how the experience fits a real sick day in an Indian household.
- Does the experience feel different?Measure distress, willingness and caregiver burden separately from whether medicine is taken correctly.
- Does it support the prescribed treatment?Compare refused, missed and incomplete doses with usual care, distinguishing scheduled medicines from those given only when needed.
- Is the design safe in use?Assess bottle fit, cleaning, materials and play pieces, including whether the character makes children more likely to seek out the medicine.
- Does interest last?Check repeated use and different medicine tastes, rather than relying only on a first, novel encounter.
Product safety assessment, clinician input and appropriately designed studies must come before claims of clinical benefit.
THE GROWN-UP STAYS IN CHARGE
Play around the moment.
Care follows the instructions.
Keep medicine in its original labelled bottle and follow its storage instructions. A carrier is not a dosing device or a child-resistant medicine container. Store medicine out of children’s sight and reach; use separate pieces for pretend play.
Follow your clinician’s or pharmacist’s directions for the medicine, dose and duration. If a child repeatedly refuses, spits out or vomits a dose, ask them what to do rather than guessing how much to give again.
