Most babies are ready to start eating baby food around 6 months of age. Some infants show signs of readiness between 4 and 6 months, but breast milk or formula is all a baby needs for the first 6 months of life. The right time depends less on the calendar and more on your baby hitting specific physical milestones that make eating safe and productive.
Signs Your Baby Is Ready for Solids
Age is a starting point, not the whole picture. Your baby needs to be developmentally ready before solid food makes sense. The CDC lists these specific signs to watch for:
- Sitting up alone or with support, with steady head and neck control
- Opening their mouth when food is offered
- Swallowing food rather than pushing it back out with their tongue
- Bringing objects to their mouth, showing interest in what you’re eating
That tongue-push reflex is worth paying attention to. Young infants automatically push foreign objects out of their mouths with their tongue. When this reflex fades, usually between 4 and 6 months, your baby can actually move food to the back of their mouth and swallow it. If you try offering food and it keeps coming right back out onto their chin, they’re not ready yet. Wait a week or two and try again.
Weight offers another useful signal. Most infants are ready for solids when they’ve doubled their birth weight or weigh above 13 pounds, according to the American Academy of Pediatrics.
Why 6 Months Is the Target
The timing isn’t arbitrary. Babies are born with iron stores they received in the womb, and those stores typically run out between 4 and 6 months. Breast milk alone can’t replace that iron fast enough, so solid foods, particularly iron-rich ones, become nutritionally important right around the half-year mark. This is one reason pediatricians recommend iron-fortified infant cereal as an early food.
A baby’s digestive system also matures significantly during this window. The gut becomes better equipped to handle foods beyond milk, and the physical coordination needed for safe swallowing develops alongside it. Starting too early, before 4 months, offers no nutritional benefit and can increase the risk of food entering the airway.
What to Offer First and How Much
You don’t need to follow a rigid order of foods, but most families start simple. At 4 to 5 months, if your pediatrician gives the green light, that typically means 1 to 2 tablespoons of iron-fortified infant cereal once or twice a day, mixed thin with breast milk or formula.
By 6 to 7 months, the menu expands considerably:
- Cereal: 2 to 4 tablespoons, twice a day
- Vegetables: about 2 ounces (a quarter cup) of pureed or well-cooked vegetables, once or twice a day
- Fruit: about 2 ounces of pureed fruit, once or twice a day
- Protein: 1 to 2 tablespoons of pureed meat, beans, or legumes, once or twice a day
These amounts are small on purpose. At this stage, breast milk or formula still provides the majority of your baby’s calories and nutrition. Solid food is a supplement and a learning experience, not a replacement. Think of the first few weeks as practice sessions where your baby figures out how to move food around in their mouth, taste new flavors, and coordinate swallowing.
Introduce one new food at a time and wait a few days before adding another. This makes it easier to spot a reaction if one happens.
Purees vs. Baby-Led Weaning
You’ll hear two main approaches: traditional spoon-feeding with purees, and baby-led weaning, where babies feed themselves soft finger foods from the start. Both are safe options, and many families end up using a mix of the two.
Baby-led weaning has gained popularity in recent years, and research supports some of its claimed benefits. Babies who self-feed tend to develop fine motor skills like precise grasping earlier, get more exposure to varied textures and food types, and show greater independence around food. In one large study, over 92% of babies using this method could decide what they ate and nearly all could regulate how much they ate, building early awareness of fullness.
The main concern parents raise is choking. The data is reassuring on this front. Multiple studies have found no significant difference in choking rates between baby-led weaning and spoon-feeding. Gagging, which looks alarming but is actually a safety reflex that pushes food forward in the mouth, is common with both methods. In one study, about 12% of baby-led weaning babies experienced a choking episode, which was statistically similar to the 11.6% rate among traditionally spoon-fed babies. Less than 1% of cases required any medical help.
Whichever method you choose, always supervise your baby during meals, keep them seated upright, and avoid known choking hazards.
Introducing Allergens Early
This is an area where guidelines have shifted dramatically. For years, parents were told to delay common allergens like peanuts, eggs, and dairy. Current recommendations from the American Academy of Pediatrics say the opposite: introduce peanut, egg, and other major allergens around 6 months of age.
This change came after landmark clinical trials showed that early introduction actually reduces the risk of developing food allergies. The updated 2021 guidelines removed the older practice of screening babies for risk level before introducing these foods. You don’t need allergy testing first, and you don’t need to wait until your baby is older. The recommendation applies to all infants, regardless of family history of allergies or eczema.
For peanuts specifically, this means offering thinned peanut butter (mixed into cereal or a puree) or peanut puff snacks that dissolve easily. Never give a baby whole peanuts or a thick spoonful of peanut butter, both of which are choking hazards.
Foods to Avoid in the First Year
Some foods are unsafe for babies under 12 months regardless of how they’re prepared. Honey is the most well-known, as it can contain spores that cause infant botulism. Cow’s milk as a drink (rather than as an ingredient in food) should also wait until after the first birthday.
Choking hazards are the bigger everyday concern. The CDC flags these specific foods to avoid or modify:
- Round, firm foods: whole grapes, cherry tomatoes, hot dogs, and sausages (all should be quartered lengthwise if served at all)
- Hard raw produce: raw carrot sticks, raw apple chunks, uncooked dried fruit like raisins
- Nuts and seeds: whole or chopped, plus thick spoonfuls of nut butters
- Sticky or hard snacks: popcorn, chips, pretzels, marshmallows, hard candy, chewy fruit snacks
- Tough proteins: large chunks of meat, bones in meat or fish, whole beans
The general rule is to avoid anything small, round, hard, or sticky. Cut soft foods into thin strips or small pieces, and mash anything that could lodge in a small airway. Foods with added sugars or low-calorie sweeteners are also not recommended for infants.
What the First Few Weeks Actually Look Like
Expect mess, rejection, and very small quantities. Most babies eat only a few spoonfuls at their first several meals. Some will spit food out, make faces, or show zero interest. This is normal. It can take 10 to 15 exposures to a new food before a baby accepts it, so don’t interpret a grimace as a permanent no.
Start with one “meal” a day, ideally at a time when your baby is alert and not too hungry. A baby who is starving wants milk, not an unfamiliar spoon. After a couple of weeks, you can add a second daily meal, and by 8 or 9 months, most babies are eating three small meals alongside their regular milk feeds. Breast milk or formula remains the primary source of nutrition through the entire first year, with solid food gradually taking on a bigger role as your baby approaches their first birthday.
