When Can Babies Start Solid Foods? Signs of Readiness and What to Feed First

How do you know when your baby is ready for solid foods?

Around 5 or 6 months, something shifts. Your baby watches you eat with intense focus. They reach for your fork. They open their mouth when you bring a spoon near them. It's one of those moments that makes you think: are we ready for this?

The answer depends less on the number of months on a calendar and more on what your baby's body is telling you. Both the American Academy of Pediatrics and the World Health Organization recommend introducing solid foods at around 6 months — not because of the number itself, but because most babies reach the necessary developmental milestones around that time. Some are ready a little earlier; some need a few more weeks.

Here's exactly what to look for, what to feed first, and how to make the transition without second-guessing every spoonful.

What are the signs a baby is ready for solid foods?

Readiness for solids isn't one single milestone — it's a combination of physical and behavioral signals that tend to show up together. The CDC and AAP both point to the same core checklist:

• Sitting up with support. Your baby can sit in a high chair or feeding seat and hold their head steady and upright without slumping. This matters for safe swallowing.
• Head and neck control. They can hold their head in a stable, upright position on their own.
• Showing interest in food. Watching you eat, reaching toward your plate, opening their mouth when food comes near — these are clear behavioral signals.
• The tongue-thrust reflex has faded. When you offer a spoon, they don't automatically push everything back out with their tongue. If food keeps coming straight back out, their reflex may not be ready yet.
• Doubled birth weight (approximately). Most babies who've reached roughly double their birth weight and are at least 4 months old are on the right developmental track, but weight alone isn't a readiness signal — it's a supporting data point.

If your baby checks all of these boxes, it's a good time to talk with their pediatrician and start the conversation about first foods.

What should you feed your baby first?

Good news: the order doesn't really matter. According to the AAP, you don't need to follow a strict sequence of vegetables before fruits, or any particular protocol. What matters is starting with single-ingredient foods and introducing them one at a time.

Iron-rich foods

Iron is the one nutrient worth prioritizing early. After about 6 months, breast milk alone doesn't supply enough iron to meet a growing baby's needs. The WHO recommends offering meat, fish, or eggs as often as possible alongside other complementary foods for exactly this reason. Iron-fortified infant cereals are another common starting point — just avoid rice cereal as the only option, since the CDC notes that exclusive rice cereal feeding can increase arsenic exposure. Oat, barley, and multigrain cereals are better choices.

Purées, finger foods, or both?

There's no wrong answer here either. Traditional spoon-fed purées and baby-led weaning (self-feeding with soft finger foods from the start) are both supported approaches when done safely. Many families land somewhere in between — soft purées for some meals, soft finger-food pieces for others. The goal is exposure to a variety of flavors and textures, not a rigid method.

A practical first-foods list

• Pureed or mashed sweet potato, squash, peas, or carrot
• Mashed ripe avocado or banana
• Pureed or finely mashed soft fruits (pear, peach, mango)
• Iron-fortified oat or multigrain infant cereal, thinned with breast milk or formula
• Pureed or very well-mashed meat (chicken, beef, turkey)
• Soft scrambled egg yolk (egg is also an early allergen to introduce — see below)

How to introduce new foods safely

The rule of thumb from the CDC: one new food at a time, and wait 3–5 days before introducing the next one. This window gives you time to notice any reactions — a rash, digestive changes, unusual fussiness — before adding another variable.

Start small. A teaspoon or two is plenty for a first taste. Your baby may spit it out, make a face, or seem completely uninterested. That's expected. Research suggests babies sometimes need 10–15 exposures to a new food before accepting it — what looks like rejection is often just unfamiliarity.

How much milk or formula during the transition?

Breast milk or formula stays the main source of nutrition through the entire first year. The WHO recommends starting with 2–3 small solid meals per day between 6–8 months, increasing to 3–4 meals by 9–11 months — always alongside continued milk feeds. Solids supplement milk; they don't replace it until after 12 months.

That balance is worth tracking. As solid meals become more established, you may notice your baby taking slightly shorter milk feeds — or you may not. Either is within the range of what's expected. Having a clear picture of both is where a feeding tracker earns its keep.

How to track feedings during the solid food transition

The 6-month mark is one of the more data-dense phases of the first year. You're still logging every milk feed, you're adding solid meals, and your baby's growth rate and diaper output are both meaningful signals during this period. Keeping a clear log — even loosely — helps you notice things: does appetite dip before a growth spurt? Are solid meals affecting how much milk your baby takes at the next feed?

Milk & Minutes lets you log both bottle feeds and nursing sessions alongside notes on solids, so you can see the full picture in one place rather than trying to hold it all in your head at 3am. The bottle insights dashboard shows daily intake trends and how your baby's milk volume is shifting over time — useful context when you're wondering whether the transition is going well. You can even share that data as a clean export for your baby's next pediatric check-in.

If you're also navigating how much to feed at each meal during this stage, our 6-month-old feeding schedule guide has age-specific amounts for both milk and solids. And if your baby is on a mix of breast milk and formula, the combination feeding guide covers how to track both without losing your mind.

What to skip in the first year

A few things to avoid entirely until after 12 months:

• Honey. It can carry Clostridium botulinum spores that are safe for adults but dangerous for infants under 1 year. The CDC and AAP are firm on this.
• Cow's milk as a drink. Small amounts in cooking or mixed with cereal are fine, but cow's milk as a primary drink before 12 months can displace iron-rich feeds and isn't nutritionally appropriate as a milk replacement.
• Added salt and sugar. Babies' kidneys aren't ready to handle much sodium, and there's no nutritional benefit to sweetening foods.
• Choking hazards. Whole grapes, raw carrots, nuts, chunks of meat, and anything that doesn't easily dissolve or mash should wait. When in doubt, make it smaller or softer.
• Juice. The AAP recommends no juice for babies under 12 months. It has minimal nutritional value and displaces milk feeds.

None of this has to feel overwhelming. Starting solids is one of those phases that sounds complicated until you're actually doing it — and then it becomes its own rhythm, one spoonful at a time.
