Locally I would advise people to phone their Child and Family Health Nurse at the community health centre. They can often give you a list of names of Paeds in the area, altho can not recommend anyone in particular.
They might be able to help you sort out some testing to start with as well.
As a mother and a nurse, and having had kids with some learning difficulties, I would always recommend seeing a Behavioural Optometrist, and also getting the child's hearing checked (ENT) since those two things are relatively easy to get sorted, and there are a lot of kids with those issues.
The paed will really be looking at sending you for other testing/specialties, so it might be a while to get anything official.
