Foods That Can Cause Constipation in Babies
The short answer
It is very common for babies to experience constipation when they begin eating solid foods. Certain foods, including rice cereal, bananas, dairy products, and low-fiber processed foods, are more likely to slow digestion. Balancing these with high-fiber foods like prunes, pears, peas, and oats can help keep your baby regular.

By Age
What to expect by age
If your baby is exclusively breastfed, constipation is rare since breastmilk is easily digested. Formula-fed babies may experience firmer stools. If you are just beginning solids around six months, the introduction of new foods can change stool consistency. Rice cereal, a traditional first food, is a common culprit for constipation. Consider starting with oat cereal or pureed fruits and vegetables instead.
As your baby eats a wider variety of solids, you may notice certain foods consistently cause harder stools. Common constipating foods include bananas, white rice, white bread, applesauce, and excessive dairy. Counter these with high-fiber options such as pureed prunes, pears, peaches, peas, beans, and oatmeal. Offering small amounts of water with meals can also help once your baby is eating solids regularly.
Toddlers who drink a lot of cow's milk often become constipated, as excessive dairy can slow digestion and reduce appetite for fiber-rich foods. Limit cow's milk to 16 to 24 ounces per day and prioritize whole grains, fruits, and vegetables. Common toddler favorites like cheese, crackers, and white pasta can also contribute to constipation when eaten in excess. Ensure adequate fluid intake throughout the day.
A diet heavy in processed snack foods and low in fruits, vegetables, and whole grains is a common cause of toddler constipation. Encouraging your child to eat a variety of fiber-rich foods and drink plenty of water is the best prevention strategy. If constipation becomes chronic despite dietary changes, your pediatrician may recommend a gentle stool softener.

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.
