Gym classes for kids near Wezembeek, WSP

Hi,

My 3 year old went to the Little Gym in Wezembeek last year and just loved it.

I am looking for something equivalent in the area, less pricy.

Has anyone tried something similar? I spotted an ad for a "cours de psychomotricité" in Woluwé Saint Pierre but can't find it.

We speak French.

Thanks!
