Is any of this happening?
Be seen today
Contact the usual healthcare team promptly if seizures become more frequent, medicines are difficult to give, feeding takes much longer than usual, or there are signs of dehydration such as much less urine, a dry mouth, or unusual sleepiness.

Does any of this apply?
Book an appointment
Arrange routine medical follow-up if there are changes in seizure pattern, feeding, growth, sleep, movement, hearing, vision, or behaviour.
Increasing coughing during meals, repeated chest infections, constipation, pain, or loss of previously used skills also deserves assessment.
