To take this further... is this belief incorrect? If you articulate it in a form that invokes literal theism, then I suppose that makes it a question of whether literal theism is correct, which obviously excludes atheists. But you could articulate it as "children are almost always a blessing" vs "children are a burden, especially after a certain number." Either of these are debatable (and truth for most people is probably a balance of the two propositions), but in this formulation, theism could be orthogonal, or it could take on an auxiliary role in supporting one over the other. And most of all, the question of whether theism is literal or whether it's a symbolic distillation of human observations about values and meaning gets factored out of practical considerations.
