How to Talk to Your Child About Hypochondroplasia

As your child grows up with hypochondroplasia, they may come to you with questions about why they look different from their peers.

“Height is just one of the many characteristics of a human’s body. All bodies vary in their shapes and sizes, and height is no different,” says David Frumberg, MD, an associate professor at the Yale School of Medicine and the director of the Yale Limb Restoration and Lengthening Program. Dr. Frumberg encourages parents to use neutral terms like “built differently” or “grows slower” instead of more negative naming.

“The goal is not to teach children to ignore or overcome their differences, but to help them understand that their worth is never defined by those differences,” says Anita M. Vitale, PhD, a pediatric psychologist at Orlando Health Children’s in Florida.

Start Early, and Talk Often

A single formal conversation can unintentionally send the message that the topic is unusual, negative, or too serious to discuss any other time, says Dr. Vitale. She recommends having open, ongoing conversations about hypochondroplasia because such a practice:

• Helps normalize the condition
• Allows children to feel comfortable bringing up thoughts, questions, or feelings whenever they come up
• Reduces stigma
• Supports healthy identity development

Use Positive Framing and Highlight Multiple Areas of Identity

Use honest, neutral language, like “You have hypochondroplasia, which means your bones grow differently and you are shorter than most people,” says Reni Pekala, a cofounder and the board director of the Hypochondroplasia Foundation, based in Dublin.

Manage Expectations and Offer Solutions

This doesn’t mean you tell your child they can do absolutely anything they want, says Pekala.

Instead, try saying something like, “You may need to do some things differently, and we will work out what helps,” says Pekala. “This acknowledges genuine experiences such as pain, fatigue, or accessibility barriers without unnecessarily limiting the child.”

Build Your Family Vocabulary

Adjust Conversations to Your Child’s Age

Children’s ability to understand their diagnosis and the questions they have about it change as they grow, says Pekala. “A preschooler may ask why they need a stool, while an older child may be thinking about height, friendships, healthcare, or independence.”

Toddlers and Preschoolers (Ages 2–5)

“Young children need to learn about body awareness, like any preschooler,” says Frumberg. “Teach them how their body grows.”

“Keep it simple,” says Pekala. “Explain that bodies come in different shapes and sizes and that their bones grow differently. Name hypochondroplasia naturally, use inclusive books, and focus on belonging and practical independence.”

Early Elementary (Ages 6–8)

“At this age, I would still emphasize the importance of caregiver modeling; it is important to be mindful of the language we use to describe your children and their differences, as they will be listening and internalizing this,” says Vitale. “As they develop more social awareness at this age, it is important to highlight that everyone has differences that make them unique.”

Explain that hypochondroplasia is a genetic condition and is not something the child caused or can “catch,” says Pekala. Discuss adaptations and how to handle respectful questions or teasing, she says.

“This is also an important age to meet other children and adults with dwarfism,” says Pekala. “Community helps children understand that they are not alone and gives them role models who share similar experiences.”

You can help your school-age child by encouraging them to explore other interests, like music, arts, and sports, so they have various aspects of their life that contribute to their self-view, says Vitale. “This is also a good age to introduce the idea that differences themselves are not inherently positive or negative. Rather, they are part of human diversity,” she says.

Tweens and Preteens (Ages 9–12+)

“Help shift away from comparisons and encourage your child not to use words such as ‘normal’ when describing the height of others,” says Vitale. “Instead, model language such as ‘typical’ or ‘average.’"

Encourage your teen to participate in healthcare decisions and connect with peers and adults with hypochondroplasia and others with short stature, says Pekala. Let them know that pride, frustration, embarrassment, and curiosity can all coexist, she says.

It is also helpful at this age to foster a sense of control, and one way to do this is through self-advocacy, says Vitale. “As the child ages, there will be more need for them to speak up for their needs, maintain self-respect, and learn to balance controllable and uncontrollable factors.”

Include Siblings in the Conversation

Include siblings as early as possible by normalizing hypochondroplasia, says Vitale. “Highlight the many ways in which all family members are similar and different from one another.”

Give your child’s siblings clear, age-appropriate information and invite their questions, says Pekala. “Acknowledge that appointments or surgery can affect the whole family. [But also] explain that fairness does not always mean everyone receiving exactly the same support.”

“These conversations can help siblings view accommodations not as ‘special treatment,’ but as ways of ensuring that everyone has an opportunity to participate fully,” says Vitale.

Teach siblings how to respond to unkind comments, but also help them develop boundaries and understand they are not responsible for protecting or caring for their sibling, says Pekala.

• “My brother is short because he has hypochondroplasia,” suggests Pekala.
• “My sister needs a step stool because her school desk was built for taller people.”
• “My brother is shorter than you, but the most interesting thing about him is …”

When your child with hypochondroplasia grows older, they may not want all information shared with siblings, so be sure to respect their privacy and preferences, says Pekala.

Build Self-Advocacy

As your child navigates school, the park, and other public settings, they may hear direct or rude questions from other people. Your response sets the emotional tone, says Pekala.

“Children learn what hypochondroplasia means partly by watching their parents,” says Pekala. When you speak about hypochondroplasia calmly, advocate confidently for accessibility, and respond to comments without embarrassment, you model that behavior for your child, she says.

That doesn’t mean you have to do it perfectly every time, says Pekala. “What matters is being willing to reflect and learn.”

“It can be helpful to frame questions from strangers as curiosity rather than criticism when appropriate,” says Vitale, who gives this example: “I see you're curious about Jimmy’s height. That's one of the things that makes him unique. He also really enjoys soccer! Do you like soccer?”

It’s also important to model healthy boundaries by declining to discuss the topic altogether sometimes, says Vitale. “Teaching children that they have control over when and how they share information supports autonomy and self-advocacy.”

“Sometimes you can simply smile or wave to stop the behavior [like staring], and then move on with your activity,” says Frumberg. “Blunt questions are tricky — often kids are simply trying to understand differences.”

• “I’m shorter because my bones don’t grow as fast.”
• “I have a condition that means I won’t get as tall as you.”
• “I don’t want to talk about that — let’s talk about … ”

Teach and Practice Positive Affirmations

Pekala recommends these books by age group:

Your child can also find confidence and positivity through community. “Connecting with other families through Little People of America in the United States or the Hypochondroplasia Foundation internationally can be valuable for both children and parents,” says Pekala. Additionally, the Chandler Project offers support throughout North America, and they hold a yearly conference to bring together researchers, families, physicians, and other members of the skeletal dysplasia community.

In these groups, children can meet peers and adults with short stature and see many different examples of how people with hypochondroplasia live, learn, work, form relationships, and participate in their communities, says Pekala.
