Baby Sleeping Through Feeds
The short answer
In the first few weeks of life, newborns should be woken to feed if they sleep longer than 3-4 hours, especially if they have not regained their birth weight. Once birth weight is regained and weight gain is established, you can generally let your baby sleep and feed on demand. Excessive sleepiness in a newborn can sometimes indicate illness or jaundice.

By Age
What to expect by age
Newborns need to eat 8-12 times per day (every 2-3 hours). In the first 2 weeks, you should wake your baby to feed if they sleep more than 3-4 hours, particularly if they have not regained birth weight. This ensures adequate calorie intake and helps establish milk supply for breastfeeding mothers. A baby with jaundice may be especially sleepy and needs regular feeding to help clear bilirubin. Once your baby has regained birth weight and is gaining well, you can begin to let them sleep longer stretches at night while still feeding on demand.
If weight gain is established, most pediatricians allow one longer sleep stretch (4-5 hours) at night. Daytime feeds should still occur every 2-3 hours. If your baby is consistently sleeping very long stretches and weight gain is a concern, continue waking for feeds.
Longer sleep stretches at night are developmentally normal. Most babies at this age do not need to be woken for night feeds if they are gaining weight well and feeding frequently during the day.
Sleeping through the night without feeding is appropriate for most babies at this age. Adequate nutrition should come from daytime feeds and solid foods.
What Should You Do?
When to take action
- Sleeping 3-4 hours between feeds in the first 2 weeks (though waking is still recommended)
- Longer sleep stretches developing after birth weight is regained and weight gain is established
- Baby feeds actively when woken and is gaining weight well
- Baby consistently sleeps more than 4 hours between feeds in the first 2 weeks
- You are having difficulty waking your baby for feeds
- Weight gain seems slow despite regular feeding
- A newborn who is very difficult to arouse, extremely lethargic, or not interested in feeding at all, which could indicate serious illness, dehydration, or infection
- Fewer than 6 wet diapers per day after day 4, or no dirty diapers when expected

Related Feeding Concerns
Baby Falling Asleep During Feeds
Many newborns fall asleep during feeding, especially in the first few weeks. The warmth, comfort, and rhythmic sucking are soothing and naturally induce sleep. This is usually normal if your baby is gaining weight well. Techniques like undressing baby, tickling the feet, or switching breasts can help keep a sleepy feeder awake long enough for a full meal.
My Newborn Sleeps Too Much
Newborns normally sleep 14-17 hours per day, and some healthy newborns sleep even more. However, in the first few weeks of life, it is important that your baby wakes to feed at least every 2-3 hours. A newborn who consistently sleeps through feedings and is not gaining weight appropriately may need to be evaluated by your pediatrician.
How Many Wet Diapers Are Enough
In the first few days, expect at least one wet diaper per day of life (1 on day 1, 2 on day 2, etc.). By day 4-5, your baby should have at least 6 wet diapers per day. This is one of the best indicators that your baby is getting enough milk. Modern diapers are very absorbent, so check by feeling the weight of the diaper.
When to Introduce Allergens to Baby
Current guidelines recommend introducing common allergens (peanut, egg, cow's milk products, tree nuts, wheat, soy, fish, shellfish, sesame) starting around 4-6 months when your baby is developmentally ready for solids. The landmark LEAP study showed that early introduction of peanuts (by 4-6 months) reduced peanut allergy risk by 80% in high-risk infants. Do not delay allergens - the old advice to wait until 1-3 years has been reversed because early exposure actually prevents allergies.
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
Could My Baby Be Aspirating During Feeding?
Aspiration occurs when food or liquid enters the airway instead of the esophagus. Signs include coughing or choking during every feed, a wet or gurgly voice after eating, recurrent chest infections, and breathing changes during meals. Silent aspiration can occur without obvious coughing. If you suspect aspiration, contact your pediatrician as a swallowing study can diagnose it.
