Yes, you can let a 5-week-old sleep through the night if they are gaining weight well and have clearance from your doctor, as some babies naturally sleep longer stretches early on; however, most newborns still need frequent night feeds (every 2-4 hours), so it's crucial to follow medical advice, ensure adequate daytime feeding, and establish a calm bedtime routine to support healthy sleep habits, rather than forcing long stretches too early.
Generally, newborns sleep about 8 to 9 hours in the daytime and about 8 hours at night. Most babies do not begin sleeping through the night (6 to 8 hours) without waking until at least 3 months of age, or until they weigh 12 to 13 pounds.
As babies grow and start to gain weight steadily, they may not need to be woken for feeds as often. By 4–6 weeks, many babies may naturally start sleeping for longer stretches at night. This happens because: Their stomach capacity increases, so they can drink more at each feed.
Most babies between 0 - 2 months require frequent feedings, including during the night, and may need to eat every 2 - 4 hours overnight. If your baby has a 10:00 PM bedtime and wakes around 7:00 AM they will likely need to feed at least 2 - 3 times overnight.
Most babies start sleeping through the night by 6 months. This means they can sleep for five to six hours at a stretch without feeding. Some babies start sleeping longer even sooner, around 4 months. It's natural and common for babies to wake up throughout the night.
Breastfed newborns often feed every 2-3 hours and formula-fed newborns every 3-4 hours – healthcare providers ususally recommend not letting babies under 3 months go longer than 4–5 hours without feeding.
Why Does SIDS Peak at 2-4 Months? The widely accepted explanation for the SIDS peak has to do with the timeline of brain development. “Up to 4 months old, the part of the brain that controls breathing and wakefulness is under a lot of development,” Juliet explains.
The 5-3-3 night feeding method is a sleep training technique where you wait 5 hours after bedtime for the first feed, then 3 hours for the second, and 3 hours for the third, using sleep training (like timed checks) for any wakes outside these windows, aiming to consolidate night sleep and encourage longer stretches by feeding only when needed within these set times. It helps babies learn to self-soothe and can reduce unnecessary night feeds, though it requires consistency and adjustment for each baby, especially breastfed infants.
Most newborns lose weight in the first few days after birth. They usually regain this lost weight within 1 to 2 weeks after birth. Until then, it's important to feed your baby often. This might mean waking your baby for a feeding, especially if it's been more than four hours since the last feeding.
The "5-5-5 Rule" for milk usually refers to breast milk storage: 5 hours at room temp, 5 days in the fridge, 5 months in the freezer (though CDC suggests longer freezer time), but it can also refer to postpartum recovery (5 days in bed, 5 days near bed, 5 days around home) for new mothers to rest and bond, emphasizing healing after childbirth. Both rules provide simple guidelines for new parents, but the storage rule has updated recommendations, and the postpartum rule's strictness varies by individual needs, according to health experts on The Bump and Franciscan Health.
Signs of dehydration in a baby may include:

10 hours before bed: No more caffeine. 3 hours before bed: No more food or alcohol. 2 hours before bed: No more work. 1 hour before bed: No more screen time (shut off all phones, TVs and computers).
Around this time, most babies cry and fuss more. This is a typical part of development and will pass in time. It usually peaks around 6-8 weeks and starts to settle at around 12-16 weeks.
Therefore, prolonged nighttime feeding—especially bottle-feeding while lying down after 6 months of age—can negatively affect a child's health in the following ways: ▪️ Increased risk of overweight, obesity, and tooth decay. ▪️ Higher incidence of chronic respiratory symptoms, including wheezing and coughing.
The hardest week with a newborn is often considered the first six weeks, especially weeks 2-3, due to extreme sleep deprivation, constant feeding demands, learning baby's cues, postpartum recovery, and a peak in inconsolable crying (the "witching hour"), making parents feel overwhelmed as they adjust to a new, exhausting routine. While the first week is tough, the challenges often intensify as the baby becomes more alert but still fussy, with major developmental hurdles like cluster feeding and increased fussiness peaking around 6-8 weeks.
The 5-3-3 rule is a loose guideline for structuring a baby's sleep schedule: 5 hours of wake time before the first nap, 3 hours of wake time before the second nap, and 3 hours before bedtime.
Share a room with baby for at least the first 6 months. Give babies their own sleep space (crib, bassinet, or portable play yard) in your room, separate from your bed. Babies in their own sleep space are at lower risk for injury and death from SIDS and situations like an adult or sibling accidentally rolling over them.
Unless their doctor tells you otherwise, let your baby sleep – they'll let you know when they need to eat! If, however, your baby hasn't yet surpassed their birth weight, or if they were premature or aren't growing as expected, you do need to rouse them to eat anytime they sleep for more than four hours straight.
When fed too much, a baby may also swallow air. This can produce gas, increase discomfort in the belly, and lead to crying. An overfed baby also may spit up more than usual and have loose stools. Although crying from discomfort is not colic , it can make crying more frequent and more intense in an already colicky baby.
As a breastfeeding mom, you may ask, "Can I go 8 hours without pumping at night?" While it's possible, it depends on factors like your milk supply, your baby's needs, and how your body responds to longer gaps between sessions.
Infants are at the highest risk for SIDS during their first 6 months of life. Most SIDS deaths occur when babies are between 1 and 4 months of age.
In contrast, there is evidence that swaddling may increase the risk of SIDS, as swaddled infants have fewer spontaneous arousals from sleep and increased sleep time, particularly during quiet sleep, which is a state of reduced arousability.
Abstract. The American Academy of Pediatrics recommends pacifier/dummy use to help prevent sudden infant death syndrome (SIDS). This recommendation is based on studies that have shown pacifier use reduces the risk of SIDS even under conditions regarded as increasing the risk of SIDS.
