Feeding challenges are one of the most common concerns new parents face. When it comes to only drinks milk from a bottle, here is what the guidelines recommend.
The short answer
Many toddlers resist giving up their bottle, especially for milk, because they associate the bottle with comfort and the familiar sucking motion. The AAP recommends weaning from bottles by 12 to 15 months, as prolonged bottle use can contribute to tooth decay, excess calorie intake, and delayed cup-drinking skills. The transition can feel difficult, but most toddlers adjust within one to two weeks.
Key takeaways
- Many toddlers resist giving up their bottle, especially for milk, because they associate the bottle with comfort and the familiar sucking motion. The AAP recommends weaning from bottles by 12 to 15 months, as prolonged bottle use can contribute to tooth decay, excess calorie intake, and delayed cup-drinking skills. The transition can feel difficult, but most toddlers adjust within one to two weeks.
- Usually normal when: Your toddler initially refuses milk from a cup but accepts it after a few days to a week of consistent offering
- Call your doctor if: Your toddler is refusing all liquids from any source and showing signs of dehydration such as dry mouth, fewer wet diapers, or lethargy
- Varies by age — see the age-by-age breakdown below
“The AAP recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, for 2 years or beyond.”
This is one of the most common questions parents ask. Searching for answers means you care.
What Parents Should Know
According to AAP, CDC guidelines, many toddlers resist giving up their bottle, especially for milk, because they associate the bottle with comfort and the familiar sucking motion. The AAP recommends weaning from bottles by 12 to 15 months, as prolonged bottle use can contribute to tooth decay, excess calorie intake, and delayed cup-drinking skills. The transition can feel difficult, but most toddlers adjust within one to two weeks. At 6-12 months, this is a good time to begin introducing milk (breastmilk or formula) in a cup alongside bottle feeds. Start with small amounts in a sippy cup, straw cup, or open cup during meals. The goal is not to eliminate the bottle yet but to build familiarity with cup drinking so the eventual transition is smoother. Many babies accept water from a cup before they accept milk. It is generally considered normal when your toddler initially refuses milk from a cup but accepts it after a few days to a week of consistent offering. However, you should contact your pediatrician promptly if your toddler is refusing all liquids from any source and showing signs of dehydration such as dry mouth, fewer wet diapers, or lethargy.
Normal vs. Concerning
By Age
What to expect by age
6-12 months
This is a good time to begin introducing milk (breastmilk or formula) in a cup alongside bottle feeds. Start with small amounts in a sippy cup, straw cup, or open cup during meals. The goal is not to eliminate the bottle yet but to build familiarity with cup drinking so the eventual transition is smoother. Many babies accept water from a cup before they accept milk.
12-24 months
The AAP recommends eliminating bottles by 12 to 15 months. If your toddler refuses milk from a cup, try offering milk in different types of cups, serving it at a slightly different temperature, or transitioning gradually by diluting bottle milk with water while offering full-strength milk in a cup. Some families find success going cold turkey and removing all bottles at once. Your toddler may drink less milk initially, which is normal. They can get calcium from yogurt, cheese, and other dairy products.
24-36 months
If your toddler is still using a bottle past age two, it becomes increasingly important to wean, as prolonged bottle use is linked to early childhood cavities, iron deficiency from excess milk intake, and picky eating. Talk to your pediatrician about a weaning plan. Some children at this age are very attached to the bedtime bottle, which is the hardest to drop. Replacing the bottle with a new bedtime routine involving a cup and a book can help.
What to Tell Your Pediatrician
- Describe when you first noticed only drinks milk from a bottle and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your toddler over 15 months refuses all liquids from any cup and will only drink from a bottle.
- Mention if your toddler is drinking more than 24 ounces of milk per day from a bottle, which may displace solid food intake.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your toddler initially refuses milk from a cup but accepts it after a few days to a week of consistent offering
- Your toddler drinks less total milk after transitioning to a cup, which is typically fine since toddlers only need 16 to 24 ounces of milk per day
- Your toddler accepts water and other liquids from a cup but is slow to accept milk from one
- Your toddler over 15 months refuses all liquids from any cup and will only drink from a bottle
- Your toddler is drinking more than 24 ounces of milk per day from a bottle, which may displace solid food intake
- Your toddler has visible tooth decay that may be related to bottle use, especially nighttime bottles
- Your child over two years has made no progress transitioning away from bottles despite consistent efforts
- Your toddler is refusing all liquids from any source and showing signs of dehydration such as dry mouth, fewer wet diapers, or lethargy
- Your toddler has significant tooth damage or pain from prolonged bottle use
What You Can Do at Home
- Keep track of when you notice only drinks milk from a bottle — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your toddler initially refuses milk from a cup but accepts it after a few days to a week of consistent offering — this is generally within the range of normal.
- At 6-12 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Offer feeding in a calm, distraction-free environment. Avoid forcing or pressuring your baby to eat.
- While monitoring at home, seek immediate care if your toddler is refusing all liquids from any source and showing signs of dehydration such as dry mouth, fewer wet diapers, or lethargy.

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.
When Does My Baby Need Amino Acid Formula?
Amino acid-based formulas (also called elemental formulas) are prescribed for babies with severe cow's milk protein allergy, multiple food protein intolerances, or conditions like eosinophilic esophagitis who cannot tolerate standard or extensively hydrolyzed formulas. They are the most hypoallergenic formula available because the proteins are broken down into individual amino acids, making allergic reactions virtually impossible.
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.
