Baby Not Drinking Enough Milk or Formula
The short answer
Babies naturally vary in how much they drink from day to day, and a temporary dip in intake is usually not concerning as long as your baby has adequate wet diapers and continues to gain weight. Babies are remarkably good at self-regulating their intake. However, a significant and sustained drop in feeding, especially in a newborn, deserves prompt attention from your pediatrician.
By Age
What to expect by age
Newborns need to eat frequently, typically 8 to 12 times per day. In the first few days, volumes are tiny (colostrum comes in teaspoons), but intake increases rapidly. By day 4 or 5, most babies should be having at least 6 wet diapers and 3 to 4 stools per day. If your newborn is excessively sleepy and not waking to eat, or is feeding fewer than 8 times in 24 hours, contact your pediatrician promptly.
Babies at this age typically consume 24 to 32 ounces of formula per day or nurse 8 to 12 times daily. There is wide normal variation. Some babies eat larger amounts less frequently, while others prefer smaller more frequent feeds. As long as your baby produces 6 or more wet diapers daily, has regular bowel movements, and gains weight steadily, they are likely getting enough.
Many babies become more efficient feeders and may nurse for shorter periods or take bottles more quickly, which can make parents worry they are not getting enough. Some babies also go through distracted phases where they are too interested in the world to focus on feeding. Offering feeds in a quiet, dimly lit room can help. Intake typically ranges from 24 to 36 ounces of formula daily.
As solid foods are introduced, it is normal for milk or formula intake to gradually decrease. Babies do not need the same volume of milk at 10 months as they did at 4 months if they are eating a variety of solids. Breast milk or formula should remain the primary source of nutrition until 12 months, but a reduction in volume is expected and healthy as solids increase.
What Should You Do?
When to take action
- Your baby drinks slightly less on some days and more on others while maintaining consistent diaper output
- Your baby's intake decreases temporarily during a minor illness like a cold
- Your older baby drinks less milk as they eat more solid foods
- Your baby feeds efficiently in 10 to 15 minutes rather than the 30 to 40 minutes they took as a newborn
- Your baby is following their growth curve despite some daily variation in intake
- Your baby's intake has dropped noticeably for more than 2 to 3 days and you are concerned about weight gain
- Your baby seems hungry and fussy but then refuses the breast or bottle when offered
- Your baby is consistently below the expected intake for their age and has slowed weight gain
- Your baby seems to be in pain or discomfort during feeds, which may indicate reflux, ear infection, or oral thrush
- Your newborn under 1 month is feeding fewer than 6 times in 24 hours or producing fewer than 6 wet diapers daily
- Your baby shows signs of dehydration: sunken fontanelle, no tears, dry mouth, or very concentrated dark urine
- Your baby is lethargic, unusually difficult to wake for feeds, or has a high fever alongside reduced feeding

Related Feeding Concerns
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.
Baby Biting Nipple While Nursing
Biting during breastfeeding is a common challenge, especially when babies start teething. It can be startling and painful, but it is almost always a phase that can be managed. Babies cannot actively nurse and bite at the same time because their tongue covers the lower teeth during proper sucking. Biting typically happens at the beginning or end of a feed when the latch is not active. With some gentle strategies, most babies learn quickly that biting ends the feeding session.
My Baby Keeps Choking on Food
First, it's important to distinguish between gagging and choking. Gagging is a normal protective reflex that helps babies learn to eat, while true choking is silent and requires immediate intervention. Most "choking" episodes parents describe are actually gagging, which is common and expected as babies explore new textures. However, if your baby frequently struggles with swallowing or shows signs of true choking, it's worth discussing with your pediatrician.
My Baby Coughs While Feeding
Occasional coughing during feeding is very common, especially in newborns who are still learning to coordinate sucking, swallowing, and breathing. It often happens with a fast milk flow or letdown. However, if your baby coughs with every feed or turns blue or has difficulty breathing, this needs medical evaluation to rule out swallowing difficulties.
Baby Falling Asleep While Nursing
It is very common for babies to fall asleep while nursing, especially in the newborn period. Breastfeeding releases hormones that make both you and your baby feel relaxed and sleepy. In most cases this is completely normal, but if your baby is not gaining weight well or consistently falls asleep within a minute or two of latching, it may be worth trying some gentle techniques to keep them feeding longer.
Baby Gagging on New Textures
Gagging on new textures is one of the most common parts of learning to eat and is a normal, protective reflex. It does not mean your baby is choking or that they cannot handle the texture. The gag reflex is positioned far forward on the tongue in young babies, which means they gag more easily. With consistent, gentle exposure, most babies gradually learn to manage new textures. Going at your baby's pace while continuing to offer varied textures is the best approach.
