Signs your baby is ready for solids
The question is almost never whether your baby is old enough. It is whether your baby is actually ready, and those are two different things. Age gets you to around 6 months and into the ballpark. The physical signs, sitting steady, good head control, and reaching for your food, tell you it is really game time.
Aim for around 6 months
Around 6 months is the target for most babies. That is when milk alone stops keeping up (iron is the big one), and when the skills for handling food usually click into place. Do not start before 4 months. If your baby was born early, use their adjusted age as context and the readiness signs below as the real guide, and loop in your pediatric or neonatal team; a preterm baby may be ready a bit later than the birthday suggests.
The readiness signs, not age alone
Before that first bite, look for these:
- Sits with little or no support and holds the position steadily.
- Steady head and neck control, held up on their own without wobbling.
- Has lost the tongue-thrust reflex, so food goes in and stays in instead of getting pushed straight back out.
- Shows interest and reaches for food, watching you eat and leaning in for a taste.
- Can bring hands and toys to the mouth, the coordination that lets them self-feed.
One sign on its own is not the green light; it is the whole picture coming together that tells you your baby is ready.
Signs that are not on the list
A few things get mistaken for readiness but are not. Waking more at night is normal and not a sign to start food early. Watching you eat is sweet but babies are curious about everything. Teeth are not required at all: gums do the mashing just fine. And bigger appetite for milk is just growth, not a cue for solids.
When to check with your pediatrician
If you are unsure whether your baby is ready, ask. Definitely check in if your baby is well past 6 months and still not sitting steadily or still pushing food out, if your baby was born preterm, or if there is a family history of food allergies so you can plan how to introduce allergens safely.
Once you are ready to start
When the signs are there, dive in. See our guide to best first finger foods, baby food textures, and gagging vs choking so you know what is normal at the table.

Frequently asked questions
What age can a baby start solids?
Aim for around 6 months. That is when most babies both need the extra nutrition (iron especially) and have the physical skills to handle food. But age is a starting point, not the whole story: the readiness signs matter just as much. If your baby hits 6 months but is not showing the signs yet, it is fine to wait a little.
Is 4 months too early to start solids?
For most babies, yes. Do not start solids before 4 months, and for the majority of babies around 6 months is the sweet spot. Younger than that, the gut and the swallowing skills are usually not ready, and starting early does not help sleep the way old advice claimed. If your pediatrician has advised starting earlier for a specific reason, follow their guidance.
My baby is 6 months but cannot sit up. Should I wait?
Steady sitting with little or no support is one of the key signs, so if your baby is not there yet, it is reasonable to wait a couple of weeks and keep checking. Good, stable head and trunk control makes eating safer. If your baby is well past 6 months and still not sitting, mention it to your pediatrician so they can take a look.
Do babies need teeth before starting solids?
No. Babies mash food with their gums just fine, and plenty of babies start solids with no teeth at all. Teeth are not on the readiness checklist. What matters is sitting steadily, good head control, losing the tongue-thrust reflex, and showing interest in food.
