Is any of this happening?
Be seen today
Seek prompt medical assessment for repeated breathing pauses, worsening chest pulling during breaths, frequent choking during feeds, or unusual sleepiness.
A newborn who cannot feed adequately or has fewer wet nappies may also need urgent assessment.

Does any of this apply?
Book an appointment
Arrange routine follow-up if feeding takes a long time, weight gain is slow, snoring is persistent, sleep is restless, or dental alignment is becoming difficult.
