I don't understand these sentences. Is the author saying that newborns up to 12 weeks behave the same way as a baby at 32 weeks in utero?????????

It is true that all the structures are essentially in place after the embryonic period. The fetal period is primarily a time of growth. However, the authors are saying that the observed behavior at 32 weeks is the same with a fetus at 40 weeks and a newborn at 4 weeks. They are saying that they could not observe any meaningful change in behavior shortly before and shortly after partruition.

Thanks...that's what I was trying to say, much less eloquently and with very bad math. :)

Do babies root in utero? (I have not observed such, but maybe some professional researcher has.)
