Baby Not Drinking Enough Milk
The short answer
Babies naturally vary how much milk they drink from day to day, and a temporary dip in intake is usually nothing to worry about. Common causes include growth pattern changes, distractibility, teething, mild illness, or simply not being as hungry on a particular day. As long as your baby is having plenty of wet diapers and continuing to gain weight along their growth curve, they are likely getting enough.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-1 month
Newborns typically eat one to three ounces per feed, gradually increasing to three to four ounces by the end of the first month. They should feed eight to twelve times in 24 hours. If your newborn is consistently taking less than the expected amount, seems very sleepy and hard to wake for feeds, or is not producing at least six wet diapers a day by day five, contact your pediatrician. Jaundice, tongue tie, and other newborn conditions can cause decreased intake.
1-3 months
Most babies consume 24 to 32 ounces of formula or an equivalent amount of breast milk per day at this age. Some babies are consistent drinkers while others vary widely from feed to feed. A temporary decrease in intake often coincides with becoming more alert and easily distracted. Try feeding in a quiet, dimly lit room if your baby seems distracted. If your baby has been sick, appetite usually returns as they recover.
3-6 months
Around four months, many babies become very interested in the world around them and may seem less interested in feeding. This is often called a "feeding strike" and is developmental, not medical. Breastfed babies may become very efficient feeders who can get a full feed in five to ten minutes, which parents sometimes mistake for not eating enough. If diaper output and weight gain are good, shorter feeds are not a problem.
6-12 months
Once solid foods begin, it is normal for milk intake to gradually decrease as food intake increases. At six to eight months, milk should still be the primary nutrition source with solids as a complement. By 12 months, aim for about 16 to 24 ounces of breast milk or formula per day. If your baby refuses milk but eats solids eagerly, try offering milk first before solids and limit juice or water that might fill them up.
1-2 years
After 12 months, toddlers need about 16 to 24 ounces of whole milk per day. Some toddlers go through phases of preferring food over milk or vice versa. If your toddler is getting dairy from other sources like yogurt and cheese, they may drink less milk. Do not force milk intake, but ensure they are getting adequate calcium and vitamin D from their overall diet.
What Should You Do?
When to take action
- Your baby drinks different amounts at each feed but the overall daily intake is consistent
- Your baby has a day or two of decreased intake during a mild illness but resumes normal feeding as they recover
- Your baby is distracted during daytime feeds but makes up for it with longer nighttime nursing sessions
- Your baby is gaining weight well and has six or more wet diapers per day
- Milk intake decreases as solid food intake increases after six months
- Your baby consistently takes less than expected for their age and weight, and weight gain has slowed
- Your baby seems interested in feeding but pulls away, cries, or arches their back during feeds, which may suggest reflux or discomfort
- Your baby has gone from an established pattern to significantly less intake for more than a few days without an obvious cause
- Your baby has fewer than six wet diapers per day, has a dry mouth, sunken eyes, or no tears when crying, suggesting dehydration
- Your newborn is not waking to eat, is increasingly lethargic, or has lost more than 10 percent of their birth weight

Related Feeding Concerns
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.
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 Clamping Down on the Spoon
Clamping down on the spoon is very common, especially during teething or when babies are learning new oral motor skills. It is often a sensory exploration behavior rather than a feeding problem. Using a soft silicone spoon and placing food on the front of the spoon can help.
How Can My Baby Get Enough Calcium Without Dairy?
If your baby cannot have dairy due to allergy or intolerance, there are many other calcium sources. These include calcium-fortified foods, broccoli, kale, tofu made with calcium sulfate, beans, calcium-fortified plant milks (after 12 months), and sardines. Breast milk and formula provide adequate calcium before 12 months. If dairy-free after 12 months, planning is important.
