Call 911
Seek emergency help if your baby or child:
Is struggling to breathe, has a sudden major change in breathing, or stops breathing
Becomes blue, grey, or unusually pale
Is unresponsive or much harder to wake than usual
Has a prolonged seizure or repeated seizures outside their care plan
Has severe choking or a suspected blocked airway
If your child has an agreed emergency or palliative care plan, follow it and contact the named service.
If you are unsure and the situation appears life-threatening, call emergency services.
Contact the child's healthcare team promptly for new feeding difficulty, repeated vomiting, fewer wet nappies, increasing sleepiness, worsening seizures, fever, signs of pain, or a change in breathing that is not immediately life-threatening.
