Yeah, that could be checking before calling the function (the caller would be
responsible for checking log_connections)

I did not imagine that much ;-) I was just seeing this code being duplicated
and just thought about to avoid the duplication. But now that I read your comments
above then I think we could just macro-ize the child_type check (as you mentioned
up-thread). That would avoid the risk to forget to update the 3 locations doing the
exact same check should we add a new child type in the game.
