Most babies are ready to start solid foods at about 6 months of age. Both the American Academy of Pediatrics and the Dietary Guidelines for Americans recommend this timeline, and introducing foods before 4 months is not recommended. But age alone isn’t the only factor. Your baby needs to hit a few physical milestones first, and the order and method you use to introduce foods can make a real difference in nutrition, allergy prevention, and long-term eating habits.
Signs Your Baby Is Ready
Somewhere between 4 and 6 months, most babies develop the physical skills they need to eat solid food. The key signs to watch for: your baby can hold their head up steadily and sit with little support. Just as important, they’ve lost what’s called the tongue-thrust reflex. Young infants automatically push food out of their mouths with their tongues. When babies are ready for solids, they start using their tongues to move food from front to back for swallowing instead.
You might also notice your baby watching you eat with obvious interest, reaching for your food, or opening their mouth when food comes near. If your baby can’t sit upright with minimal help or still pushes everything out with their tongue, give it another week or two and try again.
What to Offer First
Iron is the top nutritional priority. Babies are born with iron stores that start running low around 6 months, so iron-rich foods should be among the very first things you introduce. Good options include pureed or finely minced beef, chicken, turkey, and lamb. Eggs and fatty fish also provide iron in a form the body absorbs efficiently. Plant-based sources like iron-fortified infant cereal, lentils, beans, tofu, and dark leafy greens work too, though the iron in these foods is absorbed less readily.
Beyond iron-rich foods, there’s no strict required order. Mashed avocado, sweet potato, banana, peas, and squash are all popular early foods. The bigger goal is variety. Offering a wide range of flavors and textures in the first weeks and months helps your baby develop a broader palate over time.
Purees vs. Baby-Led Weaning
You have two main approaches, and both are valid. Traditional spoon-feeding with purees gives you more control over how much your baby eats and makes it easier to introduce one food at a time so you can watch for allergic reactions. Meal prep tends to be simpler, and the smooth textures reduce choking concerns for parents who feel nervous about starting solids.
Baby-led weaning skips purees entirely. Instead, you offer soft finger foods your baby can pick up and feed themselves. Strips of ripe avocado, steamed broccoli florets, or soft-cooked sweet potato sticks are common starting points. This approach encourages independence and may help babies regulate their own appetite more naturally, since they decide how much goes in. Research from Children’s Hospital of Orange County notes that early exposure to different textures can also reduce picky eating later.
The downsides of baby-led weaning are practical: meals are messier, and it’s harder to track exactly how much food your baby actually consumed versus how much ended up on the floor. Gagging is also more common as babies learn to manage new textures. Gagging looks alarming but is a normal protective reflex, distinct from choking. Many families blend both approaches, starting with some purees and offering soft finger foods alongside them.
Introduce Allergens Early
This is one area where guidelines have shifted dramatically in recent years. Current recommendations encourage introducing common allergens like peanut and egg early, not avoiding them. For babies with severe eczema or an existing egg allergy, the National Institute of Allergy and Infectious Diseases recommends peanut-containing foods as early as 4 to 6 months. For babies with mild to moderate eczema, around 6 months is the target. Babies with no eczema or food allergies can have peanut-containing foods introduced freely alongside other solids.
The key is consistency. For peanut specifically, the recommended amount is roughly 6 to 7 grams of peanut protein per week, spread across three or more feedings. That’s about 2 teaspoons of smooth peanut butter mixed into a puree or thinned with breast milk at each serving. Never give a baby whole peanuts or chunky peanut butter, as these are choking hazards. The same early-introduction principle applies to other major allergens: tree nuts (as butters or flours), dairy, wheat, soy, fish, and shellfish.
When introducing a new allergen, offer it in a small amount and wait a couple of days before trying another new one. This makes it easier to identify the culprit if your baby develops a reaction like hives, vomiting, or swelling.
How Much and How Often
In the beginning, solid food is a supplement to breast milk or formula, not a replacement. At 6 to 8 months, most babies eat two to three small meals of solids per day. A “meal” at this stage might be just a few tablespoons. Breast milk or formula still provides the majority of calories and nutrition, with feeds of around 3 to 4 ounces each.
By 9 months, your baby may be up to three to four meals per day plus one or two small snacks. Portions naturally increase as your baby gets more comfortable with eating and their appetite grows. The transition is gradual. By 12 months, solids become the primary source of nutrition, and breast milk or formula shifts into a supporting role.
Once your baby starts solids, you can also offer small amounts of water. Between 6 and 12 months, 4 to 8 ounces per day is appropriate. A sippy cup or open cup with a few sips at mealtimes is enough. Breast milk or formula should still be the main source of hydration.
Foods to Avoid Before Age One
A few foods are genuinely dangerous for babies under 12 months:
- Honey can contain spores that cause infant botulism, a serious form of food poisoning. This includes honey baked into foods, added to water, or spread on a pacifier.
- Cow’s milk as a drink has too many proteins and minerals for a baby’s kidneys to handle and may cause intestinal bleeding. Small amounts of dairy in cooked foods or yogurt are generally fine, but milk shouldn’t replace breast milk or formula before 12 months.
- Unpasteurized foods like raw milk, raw cheeses, or unpasteurized juices carry a risk of harmful bacteria that can cause severe diarrhea.
- High-mercury fish such as shark, swordfish, king mackerel, and tilefish can harm the developing brain and nervous system with repeated exposure.
Reducing Choking Risk
How food is prepared matters as much as what food you serve. The CDC warns that foods served uncooked, whole, or in certain shapes can be hazards. Avoid whole corn kernels, uncut cherry or grape tomatoes, whole grapes, marshmallows, and chewing gum. Hard raw vegetables, large chunks of meat, and sticky foods like globs of nut butter are also risky.
For safe preparation, cook vegetables until they’re soft enough to mash between your fingers. Cut round foods like grapes and cherry tomatoes lengthwise into quarters. Spread nut butters thinly rather than offering a spoonful. Always have your baby seated upright during meals, and stay with them the entire time they’re eating. Learning the difference between gagging (noisy, baby works the food out on their own) and choking (silent, baby can’t breathe) is worth the few minutes it takes to watch a reliable instructional video before you start solids.
