Does any of this apply?
Book an appointment
Arrange routine follow-up for recommended health monitoring.
Make a non-urgent appointment for reduced hearing or vision, persistent constipation, unusual tiredness, weight changes, loud snoring, pauses in breathing during sleep, loss of learned skills, or continuing mood or behaviour changes.
These are not routine features of Down syndrome and need assessment based on their cause.
Every sign above is quoted from the sofidex article on Down syndrome. If you are not sure, err upward — it is always reasonable to be checked.
