Feeding challenges are one of the most common concerns new parents face. When it comes to weaning from breastfeeding at 12 months, here is what the guidelines recommend.
The short answer
Weaning at 12 months is a natural transition point, as your baby can now drink whole cow's milk and is eating a variety of solid foods. The process works best when done gradually over several weeks, dropping one nursing session at a time. Your baby may find comfort in extra cuddles, a lovey, or other soothing routines as breastfeeding sessions are replaced.

What Parents Should Know
According to AAP, CDC guidelines, weaning at 12 months is a natural transition point, as your baby can now drink whole cow's milk and is eating a variety of solid foods. The process works best when done gradually over several weeks, dropping one nursing session at a time. Your baby may find comfort in extra cuddles, a lovey, or other soothing routines as breastfeeding sessions are replaced. At 6-12 months, if you are planning to wean around 12 months, you can begin preparing in the months before by introducing a cup and making sure your baby is comfortable drinking from it. Start dropping the nursing sessions your baby is least attached to, usually the midday ones, and replace them with a snack and a cup of breast milk, formula, or water. Save the morning and bedtime feeds for last, as these tend to be the most emotionally important. It is generally considered normal when your toddler asks to nurse at their usual times but can be redirected with a snack, cup, or cuddle. However, you should contact your pediatrician promptly if you develop signs of mastitis including fever, severe breast pain, and redness that are not improving.

6-12 months
If you are planning to wean around 12 months, you can begin preparing in the months before by introducing a cup and making sure your baby is comfortable drinking from it. Start dropping the nursing sessions your baby is least attached to, usually the midday ones, and replace them with a snack and a cup of breast milk, formula, or water. Save the morning and bedtime feeds for last, as these tend to be the most emotionally important.
12-24 months
At 12 months, your baby can transition to whole cow's milk, which should be offered in a cup rather than a bottle. The AAP recommends 16 to 24 ounces of whole milk per day for toddlers. Drop nursing sessions one at a time, waiting a few days between each change to allow your supply to adjust gradually. Offer your child plenty of physical affection during this transition, as breastfeeding may have been their primary comfort strategy.
What to Tell Your Pediatrician
- Describe when you first noticed weaning from breastfeeding at 12 months 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 is refusing cow's milk and other dairy and you are concerned about calcium intake.
- Mention if you are experiencing persistent engorgement, plugged ducts, or mastitis symptoms during weaning.
- 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 asks to nurse at their usual times but can be redirected with a snack, cup, or cuddle

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.
