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 much sleep your baby needs, on average: â¢ Newborns to 3 month olds: 10-11 hours at night, 4-5 hours day in 4-5 naps (short naps are common) â¢ 4 to 5 month olds: 10-12 hours at night, 2-4 hours day in 3-4 naps (at least two 1+ hour naps)
