Thanks for pointing that out. I wrote "prohibited" from what I remembered when my child was little and the discrepancy to the info you provided made me research the topic, so here is a summary of what the law (1223/2009 Cosmetic Products Regulation Annex III) has to say:

Tooth paste with more than one per mille of fluoride has either to be marked as unsuitable for children or has to have a note that children have to be supervised using it and a doctor or dentist has to be consulted in case the child swallows more than a pea-sized amount.

So, not quite prohibited, but far from recommended.
