Most health organizations recommend introducing solids around 6 months, but many pediatricians give the green light between 4 and 6 months if a baby shows clear signs of readiness. At 5 months, your baby falls right in that window, so the key question isn’t just age. It’s whether your baby’s body is ready and how to start safely.
Readiness Signs to Look for First
Age alone doesn’t determine whether your baby is ready for solids. What matters is a set of physical milestones that show their mouth, throat, and digestive system can handle food beyond milk. Before you pick up a spoon, check for these signs:
- Head and neck control. Your baby can hold their head steady and upright without wobbling.
- Sitting with support. They can sit upright in a high chair or on your lap with minimal help.
- Interest in food. They open their mouth when food comes toward them, watch you eat, or reach for your plate.
- Loss of the tongue-thrust reflex. When something enters their mouth, they swallow it rather than pushing it back out onto their chin. This reflex fades at different rates, and some 5-month-olds still have it strongly. If your baby keeps pushing food out, wait a week or two and try again.
- Grasping ability. They’re bringing objects to their mouth and trying to grab small toys or items.
If your baby checks most of these boxes, they’re likely ready. If they’re missing several, especially the ability to sit with support and swallow food forward, waiting a few more weeks is perfectly reasonable.
How Much and How Often to Start
At 5 months, solids are an introduction, not a meal replacement. Think of the first few weeks as practice sessions where your baby learns to move food around their mouth and swallow on purpose. Start with one feeding per day, offering just one to two teaspoons of a single food. Some babies will eagerly eat more; others will taste a tiny bit and lose interest. Both responses are normal.
After a week or two of successful single daily feedings, you can gradually move to two sessions per day. There’s no rush to increase volume. Your baby’s primary nutrition still comes from breast milk or formula, and that stays true through the rest of the first year. A formula-fed baby at this age typically drinks 6 to 7 ounces per feeding, five to six times a day. That volume will decrease slowly as solid food intake grows over the coming months, but for now, keep milk feeds on their usual schedule.
Best First Foods
Iron is the nutrient to prioritize. Babies are born with iron stores that begin depleting around 4 to 6 months, and breast milk alone doesn’t supply enough to keep up. Iron-rich options for first foods include iron-fortified infant cereal (rice or oat), pureed meat like chicken or beef, pureed lentils, mashed tofu, and pureed dark leafy greens. You don’t have to start with cereal. Pureed meat is one of the best sources of easily absorbed iron, and many babies take to it well when it’s blended smooth.
Beyond iron, aim for variety over the first few weeks. Mashed sweet potato, pureed peas, mashed avocado, pureed banana, and cooked pureed carrots are all good early options. Introduce one new food at a time and wait two to three days before adding another. This makes it easier to identify the source if your baby has a reaction like a rash, vomiting, or diarrhea.
Getting the Right Texture
For a 5-month-old, food should be completely smooth and thin, close to the consistency of a thick soup. Use a blender or food processor to puree cooked fruits, vegetables, or meats, then thin the mixture with breast milk, formula, or water until it drips easily off a spoon. If a puree is too thick, your baby will struggle to move it to the back of their tongue and may gag or refuse it. As your baby gets more comfortable over the coming weeks, you can gradually thicken the texture.
Introducing Common Allergens Early
Recent guidelines have shifted significantly on allergens. Introducing peanut, egg, and other common allergens early, rather than delaying them, actually reduces the risk of developing food allergies. For peanut specifically, the approach backed by clinical research involves offering a small amount of thinned peanut butter or softened peanut puffs once your baby is already tolerating a few other solid foods.
To prepare peanut butter safely for a young infant, mix 2 teaspoons of smooth peanut butter with 2 to 3 teaspoons of hot water, stir until completely dissolved and thinned, then let it cool. You can also blend it into a fruit or vegetable puree your baby already tolerates. Never give a baby a glob of peanut butter on its own, as the sticky texture is a choking risk.
For the first peanut feeding, offer a small taste on the tip of a spoon and wait 10 minutes. If there’s no reaction (no hives, swelling, vomiting, or sudden fussiness), slowly offer the rest. Plan to stay with your baby for at least 2 hours afterward to watch for any delayed signs. Do this at home, not at daycare or a restaurant, and when your baby is healthy, not during a cold or stomach bug. If your baby has severe eczema or a known egg allergy, talk with your pediatrician before introducing peanut, as allergy testing may be recommended first.
Foods to Avoid Under 12 Months
Some foods are off-limits for the entire first year. Honey is the most important one to remember. It can contain spores that cause infant botulism, a serious form of food poisoning. This applies to honey in any form: raw, cooked, or added to other foods or drinks. Cow’s milk as a drink is also not appropriate before 12 months. It contains too much protein and too many minerals for a baby’s kidneys, doesn’t provide the right nutrient balance, and can cause intestinal bleeding. Small amounts of cow’s milk cooked into foods are generally fine, but it shouldn’t replace breast milk or formula.
Beyond those two, avoid foods with added sugar (flavored yogurts, cookies, sweetened cereals) and foods high in salt (processed meats, canned foods without a low-sodium label, packaged snacks). Babies have almost no room in their small diets for empty calories. Also skip any unpasteurized foods or drinks, including raw milk, unpasteurized juice, and soft unpasteurized cheeses, which carry a risk of harmful bacteria.
Gagging vs. Choking
Nearly every baby gags when starting solids, and it looks alarming. But gagging is a protective reflex, not an emergency. The key difference: gagging is loud. Your baby will cough, sputter, or retch, and their face may turn red. They might push their tongue forward to move the food out. This is their body learning to handle new textures, and it typically resolves on its own within seconds.
Choking is quiet. If your baby suddenly goes silent, can’t cough or cry, and their gums, lips, or fingernails start turning blue, that’s a blocked airway. Get them out of the high chair immediately, support their chest and chin with one hand, and deliver five firm back blows between the shoulder blades with the heel of your other hand. Taking an infant CPR class before starting solids is one of the most practical things you can do.
Reading Your Baby’s Hunger and Fullness Cues
Let your baby set the pace. Hunger looks like leaning toward the spoon, opening their mouth eagerly, or getting excited when they see food. Fullness looks like closing their mouth when you offer a bite, turning their head away, pushing the spoon or food aside, or relaxing their hands after a period of active eating. Resist the urge to coax “just one more bite.” Respecting these cues from the start helps your baby develop a healthy relationship with eating, and it also prevents overfeeding during a stage when their stomach is still very small.
A Practical Starting Routine
Pick a time of day when your baby is alert and in a good mood, not overtired or starving. Mid-morning or early afternoon, about an hour after a milk feed, often works well. Sit them upright in a high chair or on your lap, use a small soft-tipped spoon, and offer tiny amounts. Expect most of the food to end up on their face, bib, and hands. That’s fine. The goal for the first few weeks is exposure, not volume.
A sample first week might look like this: days one through three, offer a teaspoon or two of iron-fortified infant cereal mixed thin with breast milk or formula. Days four through six, try pureed sweet potato or another single-ingredient vegetable. Day seven, you could introduce pureed meat or a fruit like banana. Keep each new food for two to three days before moving on, and continue breast milk or formula as the main source of nutrition throughout.
