Effectiveness is the capability of producing a desired result. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression.
The average newborn sleeps about 16 hours a day, but some need much less sleep and some much more. Also, it's not uncommon for a newborn's sleep pattern to change from day to day; he may sleep substantially less than usual one day and then catch up by sleeping more the following day.
How long should your baby be awake? Newborn babies generally sleep a lot (according to Dr. Weissbluth newborns average between 11 â 18 hours of sleep per 24-hour period). However baby sleep is generally broken up into 7-8 ânapsâ varying in length from 15 minutes to 4-6 hours.
