You haven't pointed to any evidence that it is important either, and that's what I asked for. The other poster rightly pointed out some citations demonstrating that the evidence for this conclusion is effectively non-existent. Absent any evidence I have no reason to accept your assertion that children "require" such interactions, particularly since it makes no sense to me. As I said, positive human interactions are clearly essential as the negative effects of isolation are dramatic, but I see no reason why peer interactions specifically are essential and there's no comparably clear, strong signal as with isolation.
