Pediatician - possible developmental disorders

the children's hospital UZ brussels in Jette has very good reputation

We've been going to UZ Brussel (neuropediatrics) with our five year old and they are indeed good. You can contact them directly they'll direct you to a right doctor. They have very wide approach and work always in teams of several specialist, both doctors of different disciplines and other healthcare personnel.

You do need to know that their written reports are only in Dutch, though you do get a (very) short English summary. All the personnel does however speak English and French and the reports are always well explained orally. Also they are better connected to the Flemish community than to Brussels area, so they are not always so great in recommending services outside the hospital in Brussels (f.ex. if you will be needing special education or kine etc. in Brussels area).
