Is checking in on the baby to see whether he or she is sleeping an OK thing to do?

Some controlled-crying experts recommend popping back in to check on your baby after some minutes of crying; to give them brief, settling controlled comforting, sometimes termed checking or visiting. But that theory can have a tendency to fail, because the baby assumes you are there to rescue him, and subsequently when you leave again, he can really crank up the crying. It can become ear-popping, crystal-cracking, blood-curdling screaming — simply because you were giving confusing signals. You see, it should take 2–20 minutes for newborns to fall asleep.  Just leave her to find the right moment to fall asleep — so long as you’re not putting baby to bed overtired every time, as that would be cruel. This system, as taught by many infant sleep experts, is simply using the process of not interfering with your wee bub as they learn how to go to sleep unaided outside the womb.
