I do agree that we don't need to go running the second they start crying because sometimes they will go right back to sleep after a few seconds to a minute of crying.
But to say that babies don't need night feedings is just a bit off the mark. Tell my breastfed babies they didn't need night feedings and see how far that would get you! It has nothing to do with training them to feed at night. Babies need round the clock feedings in the beginning to maintain their blood sugar levels, because they have very tiny tummies, and are going thru huge growth and changes their first year.
Nighttime parenting is different than day parenting. It does help to recognize that there is a difference and our little ones have different needs at night.
One big thing to realize is that there are no absolutes with babies. Babies go thru many changes and stages, especially this first year. You have to able to go with what they need when they need it. And that is what very young babies have-needs not wants.
I was able to learn a lot about baby sleep by reading Dr. Sears Baby Sleep Book, The Baby Whisperer and The No-Cry Sleep Solution. Lots of helpful info in each to help form a sleep routine th.at worked for my little ones
He is a bit too young to approach any kind of sleep training yet but you can establish good routines that he will learn what to expect and what is expected. But you would certainly want to go in, check on him and what always worked for me (when mine didn't need to nurse)was to place my hand on baby and put my head down on the side of the crib. They knew mom was there and they were comforted and felt safe.
