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.
You can help your baby sleep all night. Honestly! Newborns sleep 16 or more hours a day, but often in stretches of just a few hours at a time. Although the pattern might be erratic at first, a more consistent sleep schedule will emerge as your baby matures and can go longer between feedings. By age 3 to 4 months, many babies sleep at least five hours at a time. At some point during a baby's first year â every baby is different â he or she will start sleeping for about 10 hours each night.
