What you may notice

Symptoms can overlap with other conditions and vary between people.

  • Altered skull shape
  • Joined fingers or toes
  • Midface differences
  • Breathing difficulties in some people

Understanding care

Clinical care may include specialist craniofacial, airway and limb assessment with developmental support. A qualified clinician decides which investigations and options fit the individual situation.

When to seek help

Arrange specialist assessment for growth, feeding or developmental concerns. Breathing difficulty, loss of responsiveness or new seizures requires urgent care rather than a community review.

For severe breathing difficulty, collapse, suspected stroke, or another emergency, call local emergency services immediately. In India, call 112.

LITTLE PEOPLE. BIG FEELINGS.

It’s okay to have
a lot of questions.

A doctor visit or an unfamiliar health word can feel scary. You can ask a trusted grown-up to help you understand, one small question at a time.

01

Say how you feel.

“I feel worried” is a good place to start.

02

Ask for simple words.

“Can you explain that in a way I understand?”

03

Bring someone you trust.

A caring adult can help you ask and listen.

For children and their grown-ups. This illustration explains a conversation, not a diagnosis. An adult should seek qualified care for a child who is unwell.
