A 5-month-old is just getting started with solids, so the amounts are small: 1 to 2 tablespoons of pureed food per feeding, once or twice a day. At this age, breast milk or formula remains the primary source of nutrition, and solid food is really about practice, not calories. Your baby is learning to move food around their mouth, swallow something thicker than liquid, and experience new flavors.
How Much Food Per Feeding
Start with just 1 to 2 tablespoons of a single-ingredient puree. That’s roughly the size of a golf ball. Many babies will eat less than that at first, and that’s normal. Some days your baby might eagerly open wide for more; other days they’ll turn away after one spoonful. Both are fine.
At 5 months, one feeding of solids per day is plenty. Some babies who took to solids early (around 4 months) may be ready for a second small meal, but there’s no rush. The goal is exposure and skill-building, not filling up on purees.
Breast Milk and Formula Stay Central
Between 1 and 6 months of age, babies consume roughly the same volume of milk each day: about 24 to 30 ounces of breast milk or formula in a 24-hour period, spread across feeds of 3 to 4 ounces each. That total shouldn’t drop because you’ve added solids. Think of those tablespoons of sweet potato or oat cereal as a bonus on top of milk, not a replacement for it.
Offer solids after a milk feed or between nursing sessions so your baby isn’t too hungry to practice with a spoon and isn’t filling up on puree at the expense of the fat, protein, and calories they need from milk.
Signs Your Baby Is Ready for Solids
Not every 5-month-old is ready. Before offering food, look for these physical milestones: your baby can hold their head steady and sit upright with support, they show interest in what you’re eating, and they no longer push food out of their mouth with their tongue automatically (the tongue-thrust reflex). If your baby still pushes every spoonful right back out, give it another week or two and try again.
Reading Hunger and Fullness Cues
At this age, your baby communicates hunger and fullness clearly if you know what to watch for. Hunger looks like hands going to the mouth, turning toward the breast or bottle, lip smacking, and clenched fists. Fullness looks like a closed mouth, turning the head away, and relaxed, open hands.
These cues matter more than any tablespoon measurement. If your baby closes their mouth after half a tablespoon, the meal is over. Forcing more food past a closed mouth teaches a baby to ignore their own satiety signals, which can create problems with eating later on.
What Consistency and Foods to Start With
First foods should be finely pureed and smooth, thin enough that they slide easily off a spoon. You can thin purees with a little breast milk or formula if needed. Single-ingredient foods are best at the start so you can identify any reactions. Good options include pureed sweet potato, avocado, banana, peas, or iron-fortified infant cereal. When choosing cereal, opt for oat, barley, or multigrain varieties rather than rice cereal alone.
Introduce one new food at a time and wait a few days before adding another. This makes it easy to spot if something causes a rash, vomiting, or unusual fussiness.
Early Allergen Introduction
Current guidelines encourage introducing common allergens like peanut and egg early rather than delaying them. For babies with severe eczema or an existing egg allergy, peanut-containing foods should be introduced between 4 and 6 months to reduce the risk of developing a peanut allergy. A thin smear of smooth peanut butter mixed into breast milk or formula works well. Whole peanuts and chunky peanut butter are choking hazards and should never be given to infants.
If your baby has eczema or a known food allergy, a blood test or skin prick test may be recommended before introducing peanut to determine the safest approach.
Water at 5 Months
Babies under 6 months generally don’t need water. Breast milk and formula provide all the hydration they need. Once your baby reaches 6 months, you can offer small sips of water, about 4 to 8 ounces spread across the whole day. At 5 months, stick to milk.
What a Typical Day Looks Like
A realistic feeding day for a 5-month-old who has just started solids might look like this: four to six breast milk or formula feeds totaling 24 to 30 ounces, plus one small sitting of 1 to 2 tablespoons of pureed food, offered when your baby is alert and in a good mood. The solid meal often works well mid-morning or early afternoon, tucked between two milk feeds.
Over the coming weeks, you’ll gradually increase the amount and variety. By 7 to 8 months, most babies are eating from multiple food groups, including vegetables, fruits, proteins, unsweetened dairy like yogurt, and whole grains. But at 5 months, keep it simple: small spoonfuls, one food at a time, and let your baby set the pace.
