At 5 months, most babies are just beginning to explore solid food, and the amounts are tiny: roughly 1 to 2 tablespoons of purée per sitting, once or twice a day. Breast milk or formula remains the primary source of nutrition, providing 28 to 32 ounces daily. Solids at this stage are about practice, not calories.
That said, 5 months sits in a gray zone. The Dietary Guidelines for Americans and the American Academy of Pediatrics recommend introducing solids at about 6 months, and introduction before 4 months is not recommended. Some babies are ready a little before 6 months, while others aren’t. The answer to “how much” depends heavily on whether your baby is actually ready to eat at all.
Is Your Baby Ready at 5 Months?
Age alone doesn’t determine readiness. Before you measure out any purée, look for these physical milestones: your baby can hold their head steady and sit upright with support, they open their mouth when food approaches, and they can move food from a spoon to the back of their throat and swallow it rather than pushing it out with their tongue. That tongue-push reflex (called the extrusion reflex) is a built-in safety mechanism. If your baby still pushes most food right back out, their body is telling you to wait a few more weeks.
Showing interest in what you’re eating is a good sign, but it’s not enough on its own. Head control and the ability to swallow smooth food are the non-negotiable pieces.
How Much Food to Offer
If your 5-month-old is showing clear readiness signs, start with about 1 teaspoon of a single-ingredient purée at one meal. That’s it for the first few days. Most of it will end up on their chin. Over the course of a week or two, you can gradually work up to 1 to 2 tablespoons per sitting, offered once or twice a day.
There’s no strict rule about exact ounces because the goal isn’t to fill your baby up. You’re introducing the concept of eating: the taste, the texture, the mechanics of swallowing something that isn’t liquid. Some days your baby will eat two tablespoons happily. Other days they’ll clamp their mouth shut after one bite. Both are normal.
A realistic early schedule looks something like this: offer a small amount of purée about 30 to 60 minutes after a breast milk or formula feeding, when your baby is alert but not starving. Trying to spoon-feed a frantically hungry baby usually ends in frustration for both of you. Start with one “meal” a day for the first week or so, then add a second if your baby seems interested.
Breast Milk and Formula Stay Central
At 5 months, your baby still needs 28 to 32 ounces of breast milk or formula per day, spread across 4 to 6 feedings. Solids don’t replace any of those feedings. Think of purées as an add-on, not a substitute. Breast milk and formula provide the fat, protein, and calories your baby’s brain and body need for rapid growth, and a few spoonfuls of sweet potato can’t match that nutritional density.
If you notice your baby drinking significantly less milk after starting solids, you’re likely offering too much food or offering it at the wrong time. Always give the breast or bottle first, then offer solids afterward.
What Foods to Start With
You don’t need to follow a rigid order. The AAP says there’s no evidence that introducing vegetables before fruits (or any other specific sequence) makes a difference in long-term food preferences. Good first foods include puréed sweet potato, squash, peas, bananas, avocado, peaches, and iron-fortified infant cereal mixed with breast milk or formula until very smooth.
If you’re using infant cereals, choose oat, barley, or multigrain varieties rather than only rice cereal. Offer one new single-ingredient food at a time and wait 3 to 5 days before introducing the next one, so you can spot any allergic reaction (rash, vomiting, diarrhea) and know exactly which food caused it.
Every food should be mashed, puréed, or strained until completely smooth. At this age, babies can’t chew, so anything they eat needs to dissolve easily with saliva. Cook fruits and vegetables until they’re soft enough to mash with a fork, then blend or press them through a strainer. No chunks, no lumps, no sticky textures that could cause choking.
Early Allergen Introduction
There’s growing evidence that introducing common allergens early can actually reduce the risk of food allergies. The Dietary Guidelines for Americans specifically note that for babies with severe eczema, egg allergy, or both (which raise the risk of peanut allergy), age-appropriate peanut-containing foods should be introduced as early as 4 to 6 months. This means thinned peanut butter mixed into a purée or infant cereal, never whole peanuts or chunks, which are a choking hazard.
If your baby has severe eczema or a known egg allergy, talk to their pediatrician before introducing peanut. A skin prick test or blood test may be recommended first. For babies without these risk factors, you can introduce peanut and egg along with other early foods without special precautions.
How to Tell When Your Baby Is Done
A 5-month-old can’t tell you they’re full, but they show it clearly through body language. Signs that your baby has had enough include closing their mouth when the spoon approaches, turning their head away, and relaxing their hands (clenched fists often signal hunger, while open, relaxed hands suggest satisfaction). Leaning back or getting distracted and losing interest in the spoon are also reliable cues.
Never force the spoon in when your baby turns away. Pushing past these signals doesn’t teach them to eat more. It teaches them that mealtimes are stressful, which can create feeding problems later. If your baby only takes two bites today, that’s a successful meal. The exposure matters more than the volume at this age.
What a Typical Day Looks Like
Putting it all together, a 5-month-old who’s just starting solids might have a day that looks like this:
- Morning: Breast milk or formula feeding
- Mid-morning: Breast milk or formula, followed 30 to 60 minutes later by 1 to 2 tablespoons of puréed fruit or vegetable
- Afternoon: Breast milk or formula feeding
- Late afternoon: Breast milk or formula, optionally followed by 1 to 2 tablespoons of iron-fortified cereal (once your baby is comfortable with one meal a day)
- Evening/night: Breast milk or formula feedings as usual
The total amount of solid food for the entire day is roughly 2 to 4 tablespoons. That might seem trivially small, but it’s exactly the right amount. Over the next few months, portion sizes will increase naturally as your baby’s appetite, coordination, and interest grow. By 7 to 8 months, many babies are eating several tablespoons across two to three meals. At 5 months, you’re laying the groundwork.
