My Baby Won't Take a Bottle (Bottle Aversion)
The short answer
Bottle aversion is different from simple bottle refusal. A baby with a true aversion may become distressed at the sight of a bottle, arching away, crying, or clamping their mouth shut. This often develops after negative feeding experiences such as being forced to finish a bottle or feeding during illness. With patience and a pressure-free approach, most babies can overcome bottle aversion.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
0-3 months
Bottle aversion in very young babies can develop if they have been pressured to eat more than they want, if feeding has been associated with pain such as undiagnosed reflux, or after a medical procedure involving their mouth or throat. The most important first step is to identify and address the underlying cause. If reflux is involved, treating it can make feeds more comfortable. Once the cause is addressed, offer the bottle without pressure and let your baby decide how much to take. Never force a nipple into a resisting baby's mouth.
3-6 months
This is a common age for bottle aversion to emerge, especially in babies who have been given bottles by well-meaning caregivers who push them to finish a certain amount. Babies at this age are becoming more aware and may begin to associate the bottle with stress. To overcome this, follow your baby's cues strictly. Offer the bottle, and if they turn away, respect that signal. Never wiggle, jiggle, or force the nipple. It may take days or weeks of pressure-free offerings before your baby begins to relax around the bottle.
6-9 months
If your baby has developed a bottle aversion at this age, you may be able to offer milk through alternative methods such as a sippy cup, straw cup, or open cup while you work on the bottle aversion. This reduces pressure around the bottle while ensuring your baby continues to get adequate fluids and nutrition. Some families find that offering the bottle in a completely new environment, such as outdoors or in a different room, can help break the negative association.
9-12 months
At this age, babies with a bottle aversion can often transition directly to a cup, which may be the easiest solution. The AAP recommends weaning off bottles by 12 months anyway. If your baby will drink from a cup, there may be no need to work on bottle acceptance at all. Focus on ensuring adequate fluid and caloric intake through cups, solid foods, and continued breastfeeding if applicable.
What Should You Do?
When to take action
- Your baby turns away from the bottle when full but is otherwise calm and happy
- Your baby has a temporary reduction in bottle intake during illness or teething
- Your breastfed baby initially resists the bottle but gradually accepts it with patience
- Your baby becomes visibly distressed at the sight of a bottle, crying or arching away before the nipple even touches their lips
- Your baby consistently takes much less than expected at each bottle feed and is not making up the difference with breastfeeding
- Your baby's weight gain has slowed or you are concerned they are not getting enough to eat
- Your baby is showing signs of dehydration such as fewer than six wet diapers per day, dry mouth, or sunken fontanelle
- Your baby refuses all feeding methods including breast, bottle, cup, and syringe and has not eaten for an extended period

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.
