Newborn Reflex Development Timing

A nurse is preparing a teaching session for new parents about the development of newborns (0-1 month) during their first month of life. During this session, the nurse emphasizes the importance of recognizing the developmental milestones that are typical for this age group. One key aspect the nurse wants the parents to remember is that a typical newborn should demonstrate a reflexive behavior known as the rooting reflex. This reflex is essential for feeding as it helps the infant locate the breast or bottle.

Fill in the blank: A newborn should exhibit the rooting reflex when their cheek is stimulated, responding by turning their head toward the stimulus and making sucking motions. This reflex typically appears around ______ weeks of age and can last until about ______ weeks of age.
