You can stop worrying about this site. My youngest was 5 when we first went there, perfectly safe in more ways than one. The lakes are well away from the camping area. This has to be one of the best if not the best site I been to in France. Large pitches, very safe area and very friendly people, I'd recommend it to anyone at anytime. In fact I always carry brochures for it in my van and tell people to go there. You go and rest assured you'll have a good time.
