At five months old, most babies are either just starting solids or not quite ready yet, so the amounts are small: 1 to 2 tablespoons of a single food, once or twice a day. Breast milk or formula remains the primary source of nutrition, and solids at this stage are really about practice, not calories.
Whether Your Baby Is Ready at 5 Months
The American Academy of Pediatrics encourages parents to wait until around 6 months to introduce solids. Starting before 4 months is linked to increased weight gain and higher rates of obesity in childhood. But many babies show signs of readiness between 4 and 6 months, and your pediatrician may give the green light at 5 months if your baby can do the following:
- Sit up with support and control their head and neck
- Open their mouth when food is offered
- Swallow food instead of pushing it back out with their tongue
- Bring objects to their mouth and try to grasp small items
If your baby still pushes food out with their tongue consistently, that reflex hasn’t faded yet, and it’s worth waiting a few more weeks before trying again.
How Much Food Per Meal
For babies in the 4 to 6 month range, Stanford Medicine Children’s Health recommends these portions per sitting:
- Iron-fortified cereal: 3 to 5 tablespoons of single-grain cereal mixed with breast milk or formula
- Fruits: 1 to 2 tablespoons of plain, strained fruit
- Vegetables: 1 to 2 tablespoons of plain, strained vegetables
That’s not all three at once. When you’re first starting out, you’ll offer just one food at a time, in a small amount. A realistic first meal looks like a tablespoon or two of pureed sweet potato or iron-fortified rice cereal thinned with breast milk. If your baby eats it and wants more, you can offer another tablespoon. If they eat two bites and turn away, that’s a perfectly fine meal at this age.
Most 5-month-olds eat solids once or twice a day at most. You’re not replacing a milk feeding. You’re adding a few tablespoons of food alongside the milk feedings your baby is already having.
Breast Milk and Formula Still Come First
At 5 months, your baby needs 28 to 32 ounces of formula per day, spread across 4 to 6 feedings. If you’re breastfeeding, that’s roughly 6 to 7 nursing sessions in 24 hours. UC Davis Health puts formula feedings at 5 to 7 ounces every 4 to 6 hours for this age.
Solids should not cut into these volumes. A common approach is to nurse or bottle-feed first, then offer solids about 20 to 30 minutes later. This way your baby gets the bulk of their nutrition from milk and approaches food relaxed rather than ravenously hungry. If you notice your baby drinking noticeably less milk after starting solids, you’re likely offering too much food.
What to Feed First
Iron is the most important nutrient to target when starting solids. Babies are born with iron stores that begin to deplete around 6 months, so foods rich in iron are ideal first choices. Iron-fortified infant cereal is a classic starter, but pureed meats like chicken, turkey, or beef are also excellent early foods because the type of iron in meat is more easily absorbed.
Other good options include pureed lentils, tofu, and dark leafy greens. Pairing these with vitamin C-rich foods like sweet potato, broccoli, or a small amount of pureed berries helps your baby absorb more iron from plant-based sources.
Introduce one new food at a time and wait two to three days before adding another. This makes it easier to identify the cause if your baby has a reaction like a rash, vomiting, or diarrhea.
Early Allergen Introduction
Current guidelines support introducing common allergens like peanut and egg early rather than delaying them. For babies with severe eczema or an existing egg allergy, introducing peanut-containing foods as early as 4 to 6 months can actually reduce the risk of developing a peanut allergy. The key is using age-appropriate forms: a thin smear of peanut butter mixed into a puree, never a whole nut or a thick glob. If your baby has eczema or a known allergy, talk to your pediatrician first, as they may recommend allergy testing before introduction.
How to Tell Your Baby Is Full
At this age, babies communicate fullness clearly once you know what to look for. They close their mouth, turn their head away from the spoon, and relax their hands. Hungry babies tend to lean forward, open wide, and get excited at the sight of food.
Resist the urge to coax your baby into finishing what’s on the spoon. Letting them decide when they’re done helps build healthy self-regulation around eating. Some days your baby will eat three tablespoons enthusiastically. Other days, they’ll take two bites and be finished. Both are normal.
Foods and Textures to Avoid
Everything you offer a 5-month-old should be smooth and thin, closer to a thick liquid than actual food. As your baby gets more comfortable, you can gradually thicken purees, but at the start, runnier is safer.
Choking hazards to avoid entirely at this stage include:
- Raw vegetables or fruit like carrots and apples
- Whole grapes, berries, or cherry tomatoes (even when mashed, grapes should be quartered)
- Nuts, seeds, or chunks of nut butter
- Hot dogs, sausages, or tough chunks of meat
- Popcorn, chips, crackers, or cookies
- Whole corn kernels or whole beans
- Marshmallows or chewing gum
Water at 5 Months
Babies under 6 months don’t need water. Breast milk and formula provide all the hydration they require. Once your baby reaches 6 months, you can start offering small sips of water, around 4 to 8 ounces spread throughout the day. At 5 months, skip the water and stick with milk.
