Supporting the Siblings of a Child with Gross Motor Delay
Siblings of a child with gross motor delay are supported through honest age-appropriate explanations, protected one-to-one time, light optional ways to help, and openness to feelings like jealousy or guilt. Watch for withdrawal or behaviour changes and seek a friendly counsellor or paediatrician if needed. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional.

When one child needs extra support to move and grow, their brothers and sisters quietly carry feelings too — and they thrive when seen, heard and included.
In short
Supporting siblings of a child with gross motor delay means giving them honest, age-appropriate explanations, protecting one-to-one time just for them, letting them help in small joyful ways without making them little carers, and watching for quiet feelings like worry, jealousy or guilt. Siblings do best when the family treats the delay as one part of a happy, ordinary home life — not its whole story. With a little intention, brothers and sisters often grow up especially kind, patient and confident.
Ways to support the siblings
- Explain in simple, true words. Tell them their brother or sister's muscles need extra practice to learn to sit, crawl or walk — and that therapy helps. Children imagine far scarier things in silence than the gentle truth.
- Protect their own time. Even ten unhurried minutes a day that belongs only to them — a story, a game, a chat — tells a sibling they matter just as much.
- Let them help, lightly. Cheering on a milestone, passing a toy during play practice, or clapping at therapy goals builds pride. Keep it fun and optional; never let a child become a substitute carer.
- Welcome every feeling. Jealousy, frustration, embarrassment in front of friends, or guilt are all normal. Name them kindly: "It's okay to feel cross when things feel unfair."
- Keep their world whole. Their hobbies, friendships and celebrations deserve full attention too, so family life feels balanced.
- Connect them with others. Knowing other children have a sibling who learns differently eases that sense of being the only one.
When to seek a little extra help
If a sibling becomes withdrawn, unusually clingy, angry, or shows changes in sleep, appetite or school, a friendly chat with your paediatrician or a counsellor can help. These are signals a child is carrying more than they can say — and they respond beautifully to a bit of focused support.
The Pinnacle way
We see the whole family, not just one child. Our therapists coach parents on simple ways to include siblings in physiotherapy goals and everyday play, so progress becomes a shared family joy. AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or online form.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for a sibling becoming withdrawn, unusually clingy, angry or resentful, or changes in sleep, appetite or school behaviour — signs they may be carrying more worry than they can express.
In everyday life
Give each sibling ten unhurried minutes a day that belongs only to them — a story, a game or a chat — so they feel just as seen and valued.

Bring your questions to a first visitQuestions families ask
Should I tell my other children about their sibling's gross motor delay?
Yes — in simple, honest words suited to their age. Explaining that their brother or sister's muscles need extra practice to learn to sit, crawl or walk, and that therapy helps, reassures them far more than silence. Children often imagine something scarier than the gentle truth.
Is it okay to let a sibling help with therapy activities?
Absolutely, as long as it stays fun and optional. Cheering a milestone, passing a toy during play practice or clapping at goals builds pride and closeness. Just be careful not to let a child take on a carer's role — they need to remain a sibling, not a helper.
My older child seems jealous and guilty at the same time. Is that normal?
Very normal. Siblings often feel jealous of the extra attention and then guilty for feeling that way. Name these feelings kindly and let them know all emotions are allowed. If the feelings seem to weigh heavily or change their behaviour, a friendly counsellor can help.
