Hard to say without knowing exactly what your child needs (they’re all different!).
Paediatrician or CAHMS for adhd medication?
Speech and language therapist? (Language, social skills including recognising emotions/needs of others)
Occupational therapist? (Movement - for the adhd particularly - calming/sensory activities, zones of regulation etc for emotional regulation)
Key as a parent is understanding the WHY - when you know the triggers and why they are behaving in a certain way, it’s easier to work out strategies to help
