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.
Your baby needs a lot more sleep than you do. Over a 24-hour period, the average newborn sleeps for 16 hours. Even at three months, your baby will need to sleep for about 15 hours over the course of 24 hours.Your baby won't take all her sleep in one long stretch, even at night.At first she'll need to wake up for feeds. From when she's newborn to when she's three months old, your baby will sleep in sleep-wake cycles through the day, with longer spells at night. The length of these sleep cycles depends on your baby.y then, most babies enjoy about 11 hours of sleep at night, with the odd brief waking, and two daytime naps of about one hour 30 minutes each. By 12 months your baby may sleep for between 12 hours and 14 hours over the course of 24 hours, including two daytime naps. By about 18 months, naps will reduce to one a day.
