For more on marking an answer as the "Best Answer", please visit our FAQ.They don't need to be clever. Evolution takes care of all that. If those who had a tendency to cry at night just so happened to have better odds of surviving, because there was no sibling coming along soon after to divide the resources and parental attention, then that trait will build up in subsequent generations. If there is anything in the theory at all, the baby doesn't do it to achieve that effect, they do it and it happens to achieve it instead. Intent doesn't come into it.
