Routine follow-up is important even when the child seems well.
Contact the regular care team about increasing joint pain, reduced movement, new walking difficulties, hearing or vision changes, dental problems, skin sores, or trouble eating.
These concerns are not usually emergencies, but earlier support may reduce their effect on daily life.
