I'm quite sceptical about asking general questions like "are vlcaks good with children". Some are, and some aren't.
It's like asking "Are vlcaks shy?" or "Are Americans fond of children?" or something similar.
CSV are pack animals and this fact determines their attitudes to pack members. I suppose it also depends on the position of the kid within the pack.
However, if they like or dislike children from outside their pack is probably an individual feature, rooted in genetics, the level of socialisation and earlier experiences.
