Dot Com Digital from 2Simple reminded me of the Think You Know website, with its cartoon-based resources. Although, as far as I know, there are no explicit links between the two sets of resources, what they have in common (apart from appearance) is that both have been developed in collaboration with the police. This is a good thing because the police have first hand experience of what can happen if issues aren't picked up early enough.

Dot Com models behaviour for children, and helps them notice their feelings and talk about them, so it addresses wellbeing too. Worth exploring further.
