Babies can start eating solid food at about 6 months old. Both the American Academy of Pediatrics and the World Health Organization recommend exclusive breastfeeding or formula for the first 6 months, then introducing complementary foods alongside milk. Starting before 4 months is not recommended.
Why 6 Months Is the Target
Around 6 months, a baby’s nutritional needs begin to outpace what breast milk or formula alone can provide. Iron stores built up during pregnancy start running low, and calories from milk may not be enough to fuel the rapid growth happening at this stage. At the same time, a baby’s digestive system and motor skills have matured enough to handle foods beyond liquid.
If solid foods aren’t introduced around this time, growth can start to falter. But introducing them too early carries its own problems. Research from Johns Hopkins found that infants who started solids before 3 months had significantly higher levels of certain fatty acids in their gut by 12 months, a pattern linked in adults to increased risks of obesity, diabetes, and high blood pressure. Earlier studies also show that children who begin solids before 6 months are more likely to be overweight in childhood and may face higher chances of developing eczema, food allergies, and asthma.
Signs Your Baby Is Ready
The calendar matters, but so does your individual baby. Not every 6-month-old is ready on the dot. The CDC lists these developmental milestones to watch for:
- Head and neck control: Your baby can hold their head steady without wobbling.
- Sitting up: They can sit upright alone or with support.
- Interest in food: They open their mouth when you bring food toward them.
- Tongue reflex fading: They swallow food instead of pushing it back out with their tongue. This tongue-thrust reflex is a built-in protection against choking in younger infants, and it needs to fade before solids will work.
- Reaching and grasping: They bring objects to their mouth and try to grab small items like toys or food.
If your baby checks most of these boxes around 6 months, they’re likely ready. If they’re closer to 5 months and showing every sign, talk to your pediatrician. The firm floor is 4 months: no solids before that point, regardless of how interested your baby seems.
How Much to Offer at First
First meals are tiny. Start with 1 or 2 tablespoons of a single food and watch how your baby responds. At this stage, the goal isn’t calories. It’s practice. Your baby is learning to move food from the front of their tongue to the back and swallow it, which is a genuinely new skill.
Breast milk or formula remains the primary source of nutrition for the entire first year. Solid food supplements it rather than replaces it. Over time, aim for something to eat or drink about every 2 to 3 hours, which works out to roughly 3 small meals and 2 to 3 snacks per day. But in the first few weeks, one or two “meals” a day is plenty. Let your baby’s hunger and fullness cues guide you rather than a strict schedule.
Best First Foods
There’s no single correct first food, but iron-rich options deserve priority. Your baby’s iron needs spike at 6 months, and breast milk alone can’t keep up. Good sources include iron-fortified infant cereal, pureed meats like beef or chicken, mashed beans and lentils, and tofu. Pairing these with vitamin C-rich foods (think mashed sweet potato, pureed berries, or a bit of tomato) helps your baby absorb more of the iron.
Beyond iron, variety matters. Introduce vegetables, fruits, and proteins one at a time, waiting a few days between new foods so you can spot any reactions. Single-ingredient purees make this easy. There’s no evidence that starting with vegetables before fruits prevents a sweet tooth, so don’t stress about the order.
When to Introduce Allergens
The advice on allergenic foods has reversed in recent years. Delaying peanuts, eggs, and other common allergens used to be standard. Now, guidelines from the National Institute of Allergy and Infectious Diseases recommend the opposite: introducing peanut-containing foods early actually reduces allergy risk.
For babies with severe eczema or an existing egg allergy, peanut-containing foods should be introduced as early as 4 to 6 months, ideally after allergy testing. For babies with mild to moderate eczema, peanut foods can be introduced around 6 months at home without testing. For babies with no eczema or food allergies, peanut and other allergenic foods can be introduced freely alongside other solids.
A thin peanut butter spread mixed into a puree works well. Never give a baby whole peanuts or chunks of peanut butter, which are choking hazards.
Texture Progression by Age
At 6 months, start with smooth, thin purees. Think the consistency of yogurt or slightly thinner. As your baby gets comfortable swallowing (usually within a few weeks), thicken the texture to mashed foods with small soft lumps. By 8 to 9 months, most babies can handle finely chopped soft foods and are starting to pick up small pieces with their fingers. By 12 months, many are eating modified versions of family meals cut into small, safe pieces.
Moving through textures matters. Babies who stay on ultra-smooth purees too long can have a harder time accepting chunkier foods later. Follow your baby’s lead: if they’re managing the current texture well and seem interested in what’s on your plate, it’s time to advance.
Foods to Avoid Before Age 1
Some foods are dangerous for babies regardless of how well they’re eating solids. The CDC flags these common choking hazards:
- Whole grapes, berries, or cherry tomatoes (cut these into quarters)
- Raw hard vegetables or fruit like carrots and apples
- Whole corn kernels
- Raisins and other dried fruit
- Marshmallows and chewy fruit snacks
- Whole pieces of canned fruit
Honey is off-limits until 12 months due to botulism risk. Juice is also not recommended before age 1. You can offer small sips of water starting at 6 months, about half a cup to one cup per day, in an open or sippy cup. But milk and solids should be doing the heavy nutritional lifting.
What the First Weeks Look Like
Expect mess, faces, and rejection. Most of that first spoonful will end up on your baby’s chin, bib, or the floor. This is normal. Your baby may grimace at new flavors, turn their head away, or spit food out entirely. That doesn’t mean they hate it. Research consistently shows it can take 10 to 15 exposures to a new food before a baby accepts it, so keep offering without pressure.
Gagging is also normal and different from choking. Gagging is loud, visible, and your baby will usually work through it on their own. Choking is silent, with no coughing or sound. Knowing the difference, and knowing infant CPR, gives most parents the confidence to let their baby explore food safely.
