The Neurobiological Mechanisms of Sleep Training in Rats

In rats, we see it from the birth to about 15 days of age they go from an oscillator that is just going back and forth randomly to one that is now being structured by the day night cycle. In humans, it takes about three to four months. And so prior to that, there's nothing, I believe, that anybody can do to change the fact that the baby is just going to cycle back and forth and not sleep through the night. So maybe you could push it around a little bit of external influence of a parent. Maybe you can make it happen, but until those connections are made, I don't think there's anything that can be done about that.
