INFANT SLEEP PATTERNS

In the first three months, tiny babies seldom sleep for more than four-hour stretches without needing a feeding. Tiny babies have tiny tummies. Yet, they usually sleep a total of 14-18 hours a day.

From three to six months, most babies begin to settle. They are awake for longer stretches during the day and some may sleep five-hour stretches at night. Between three to six months, expect one or two nightwakings. You will also see the period of deep sleep lengthen. The vulnerable periods for nightwaking decrease and babies are able to enter deep sleep more quickly. This is called sleep maturity.

Generally, newborns sleep about eight to nine hours in the daytime and about eight hours at night. Most babies do not begin sleeping through the night (six to eight hours) without waking until about three months of age, or until they weigh 12 to 13 pounds. Newborns and young infants have a small stomach and must wake every few hours to eat. In most cases, your baby will awaken and be ready to eat about every three to four hours.

It is not necessary to wake a baby for feedings unless you have been advised to do so by your baby's physician. However, we usually do not let a newborn sleep longer than five hours at a time in the first five to six weeks. Some premature babies need more frequent feedings and must be awakened to eat.

Babies have shorter sleep cycles than you do. Alternating light and deep sleep about every 60 minutes vs Adults 90 minutes.

Signs that baby is falling asleep:
o Sigh Baby
o Grimace Baby
o Flutter Baby
o Twitch Baby
o Limp-limb Baby is usually fast asleep

Some babies need help getting back to sleep. Some "resettlers" or "self-soothers" can go through this vulnerable period without completely awakening, and if they do wake up, they can ease themselves back into a deep sleep.

Blood flow to the brain nearly doubles during REM sleep. (This increased blood flow is particularly evident in the area of the brain that automatically controls breathing.) During REM sleep the body increases its manufacture of certain nerve proteins, the building blocks of the brain. Learning is also thought to occur during the active stage of sleep. Speak with your pediatrician regarding your babies sleep habits as all babies differ.

Your Baby's Reflexes

Instincts are powerful. Your baby is born with instinctive reflexes that assist in survival.

Here's a quick review of a few of your baby's reflexes, to help you marvel at your newborn.

• Moro or “startle” reflex: This occurs when your baby's head shifts position quickly. Or when her head falls backward. Or when your baby is startled by something loud. She will react by throwing out her arms and legs and extending her neck. Your baby will then quickly bring her arms together. She may cry when doing this. This reflex should go away after two months.
• Rooting reflex: This is how your baby hunts for her mother's breast. If you gently stroke the side of her cheek with your finger, she will turn her head toward your finger. This lasts for three to four months.
• Grasp reflex: Your baby will clench her fist around anything pressed into the palm of her hand. You can show this to a big brother or sister. Say, “The baby wants to hold on to your finger.” This reflex goes away at five to six months.
• Stepping reflex: If you hold a newborn baby upright under her arms with her feet on a hard surface, her feet will make a stepping action. This happens even though it is a long time before she is ready to stand or walk. This usually lasts a couple of months.

Ask your pediatrician if you have any questions about your baby's reflexes.
