Answer:
Infants sleep between 9 and 12 hours during the night and nap between 2 and 5 hours during the day. At 2 months, infants take between two and four naps each day, and at 12 months, they take either one or two naps. Expect factors such as illness or a change in routine to disrupt your baby’s sleep. Developmental milestones, including pulling to a standing and crawling, may also temporarily disrupt sleep.
By 6 months of age, most babies are physiologically capable of sleeping through the night and no longer require nighttime feedings. However, 25%-50% continue to awaken during the night. When it comes to waking during the night, the most important point to understand is that all babies wake briefly between four and six times. Babies who are able to soothe themselves back to sleep (“self-soothers”) awaken briefly and go right back to sleep. In contrast, “signalers” are those babies who awaken their parents and need help getting back to sleep. Many of these signalers have developed inappropriate sleep onset associations and thus have difficulty self-soothing. This is often the result of parents developing the habit of helping their baby to fall asleep by rocking, holding, or bringing the child into their own bed. Over time, babies may learn to rely on this kind of help from their parents in order to fall asleep. Although this may not be a problem at bedtime, it may lead to difficulties with your baby falling back to sleep on her own during the night.
Safe Sleep Practices for Infants
Practice the ABC’s of safe sleep: Babies should always sleep Alone, on their Backs, in a Crib. Place your baby on his or her back for every sleep, night time and nap time.
Do not put your baby to sleep on his side or tummy.
Once your baby can roll from his back to tummy and tummy to back, your baby can stay in the sleep position that he assumes. But always place your baby to sleep on his back.
Place your baby on a firm mattress in a safety-approved crib with slats no greater than 2-3/8 inches apart.
Make sure your baby’s face and head stay uncovered and clear of blankets and other coverings during sleep. If a blanket is used make sure your baby is placed “feet-to-foot” (feet at the bottom of the crib, blanket no higher than chest-level, blanket tucked in around mattress) in the crib. Remove all pillows from the crib.
Create a “smoke-free-zone” around your baby.
Avoid overheating during sleep and maintain your baby’s bedroom at a temperature comfortable for an average adult.
Remove all mobiles and hanging crib toys by about the age of 5 months, when your baby begins to pull up in the crib.
Remove crib bumpers by about 12 months, when your baby can begin to climb
