Yes, it’s common for newborns to show little interest in eating, especially in the first 24 to 48 hours of life. Many babies are recovering from the work of being born, and their tiny stomachs need very little at first. On day one, a newborn’s stomach holds only about 5 to 7 milliliters, roughly one teaspoon, per feeding. That said, there’s a difference between a sleepy baby who needs gentle coaxing and one who is refusing to eat because something is wrong.
What Normal Newborn Feeding Looks Like
In the first weeks, babies typically eat 8 to 12 times in a 24-hour period, or about every 1 to 3 hours. But those numbers represent an average across the early weeks. In the very first day or two, many healthy babies sleep heavily and show minimal hunger cues. This doesn’t necessarily mean something is wrong.
A newborn’s stomach grows rapidly. By day three, it holds about 22 to 27 milliliters (4 to 5 teaspoons). By the end of the first week, capacity jumps to 45 to 60 milliliters, or roughly 1.5 to 2 ounces per feeding. Because the stomach starts so small, your baby genuinely doesn’t need much at each feeding in those earliest days. Short, frequent sessions are the norm, and what looks like “not eating” may actually be your baby taking in exactly what they need.
Why Some Newborns Are Hard to Wake for Feeds
Birth is exhausting. Babies who had a long labor, were born slightly early, or were exposed to pain medication during delivery often sleep more deeply and are harder to rouse. Premature babies and those with low birth weight may have less mature brain development, which can make automatic processes like waking for hunger slower to kick in. Multiples (twins, triplets) tend to be smaller and may also be sleepier than average.
This deep sleepiness usually improves within 48 to 72 hours as the baby adjusts to life outside the womb. Until then, you may need to actively wake your baby for feedings rather than waiting for hunger cues.
How to Tell Your Baby Is Getting Enough
Since you can’t measure exactly how much a breastfed baby drinks, output is your best clue. In the first few days, expect at least one wet diaper per day of life (one on day one, two on day two, and so on). After day five, a baby getting enough milk will produce at least six wet diapers a day. Stools also shift: the first bowel movements are black and sticky, transitioning to mustard-yellow and seedy by around day five.
During feedings, watch for signs of actual milk transfer. A baby who is latched well and swallowing will fall into a rhythmic pattern of suck-suck-swallow or suck-swallow. You may feel a fluttering sensation in your breast as they feed. A baby who is only doing shallow, rapid sucking with very little swallowing may not be getting milk effectively, even if they’re on the breast for a long time. After a good feeding, babies often release the breast on their own and look relaxed or drowsy.
Weight loss in the first few days is normal. Most newborns lose some of their birth weight before milk supply fully comes in. A loss of up to 7 to 10 percent is generally expected, and babies typically regain their birth weight by about two weeks of age.
Jaundice Can Make Babies Sleepier
One of the most common medical reasons a newborn seems uninterested in eating is jaundice, a buildup of a substance called bilirubin that turns the skin and whites of the eyes yellowish. Mild jaundice is extremely common and usually harmless, but it creates a frustrating cycle: jaundice makes babies sleepy, sleepy babies breastfeed less enthusiastically, and less frequent feeding can make jaundice worse.
If your baby’s skin looks increasingly yellow, especially spreading to the chest and belly, and they’re becoming harder to wake, the bilirubin level may need to be checked. Very high levels can cause hearing loss, seizures, and brain damage, but this is rare when jaundice is caught and treated early. Treatment typically involves light therapy and more frequent feedings to help the baby’s body clear the bilirubin.
Tricks to Wake a Sleepy Baby
Start gentle. Talk to your baby, sing, rub their cheek, or tickle the bottoms of their feet. Moving their arms and legs around can help bring them to a lighter stage of sleep. Undressing your baby down to a diaper often works because the slight change in temperature is stimulating enough to get their eyes open.
If undressing alone doesn’t work, try a diaper change, even if the diaper is clean. The process of being moved, wiped, and handled tends to wake even deeply sleepy babies. This is especially useful for babies who latch on but fall asleep before finishing a feed. Skin-to-skin contact, where you hold the undressed baby against your bare chest, can also trigger feeding instincts and encourage them to root and latch.
Signs That Something May Be Wrong
A baby who misses two or more feedings in a row, or who latches but doesn’t swallow, needs to be evaluated. The same goes for a baby who is sleeping significantly more than usual and is very difficult to wake. These are different from the normal deep sleepiness of the first day or two.
Other signs to watch for include:
- Fewer wet diapers than expected for the baby’s age, a dry mouth, or crying without tears
- Floppiness or limpness when you pick the baby up, beyond normal newborn head control
- Fever of 100.4°F (38°C) or higher in a baby under three months
- A sunken soft spot on the top of the head, which can indicate dehydration
- Persistent vomiting after feeds, not just normal spit-up
- Unusual fussiness or high-pitched crying that is very different from normal newborn crying
Any of these warrants a call to your baby’s pediatrician or a visit to urgent care. In the first few weeks, it’s always reasonable to call if something feels off. Feeding problems caught early are almost always easier to fix than those that go unaddressed for days.
When Feeding Typically Picks Up
Most parents notice a clear shift around day two or three. This often coincides with the transition from colostrum (the thick, concentrated early milk) to more mature milk in breastfeeding mothers, and with the baby becoming more alert after recovering from birth. By the end of the first week, feedings tend to become more predictable, the baby wakes on their own more often, and diaper counts climb.
If you’re breastfeeding and your baby is still difficult to feed by day three or four, a lactation consultant can assess the latch and help identify whether the baby is transferring milk effectively. Sometimes what looks like a disinterested baby is actually a baby struggling with a shallow latch or a tongue tie that makes feeding uncomfortable. Small adjustments to positioning can make a surprising difference.
