Feeding therapy for a 4-year-old

Hello! I don't know how much you use the internet to find doctors or health advice, but I always look for and find new doctors on the online booking platform Doctena. You can filter by the specialty you need, the location and the language you prefer there! This is the page link: https://www.doctena.be/en/
I hope it helps :)

You could try the Brussels Childbirth Trust for recommendations. Or the Community Help Service.
