When can babies start solid foods? Most babies can begin at about 6 months, and you should not introduce solids before 4 months. [1] Breast milk or infant formula remains part of feeding as solids begin. [2]
Starting solids is a gradual change in how your baby eats, not a sudden switch away from breast milk or formula. As you think about timing, keep those familiar feeds in your baby’s routine while solids are added.
What readiness looks like
Readiness is best judged alongside your baby’s age, not by one milestone alone. A single change—such as reaching a certain weight—does not tell you on its own that your baby is ready for solids.
Think about the bigger picture when you discuss timing with your baby’s health care professional. You might share how old your baby is, what changes you have noticed, and what is making you consider solids; that gives you a chance to ask how those details fit together for your child.
Weight can be one detail in the conversation, but avoid using weight or doubled birth weight alone as the green light. The American Academy of Pediatrics describes babies who have doubled their birth weight, typically at about 4 months, and weigh about 13 pounds or more as potentially ready—not as a stand-alone rule for every baby. [3]
If you are unsure how to weigh age and development together, bring that question to your baby’s health care professional. You do not need to make the decision from one number or one observation.
When timing may need a conversation
If your baby is younger than 4 months, wait before introducing solid foods; if your baby is nearing 6 months and you are unsure about readiness, ask their health care professional. [1] A broad 4-to-6-month range can make the timing sound more flexible than the practical guidance suggests, so focus on your baby’s age and discuss questions as they approach 6 months.

If your baby is younger than 4 months
Hold off on solids for now. For example, if your 3-month-old watches you eat or seems interested in food, those moments are not a reason to begin solids early. [1] You can make a note of what you notice and bring it up at a future health care visit. You may also find this useful: How to Make Baby Food at Home, Step by Step.
If you are unsure near 6 months
Ask your baby’s health care professional for help thinking through the timing. [3] You might say, “My baby is almost 6 months, and I’m not sure they’re ready—what should I look for?” A specific question can help you get guidance that fits your baby, rather than relying on a general age range.
You do not need to settle the question on your own. If you are uncertain as your baby approaches 6 months, make it a topic for your next conversation with their clinician.
What to do next
Once you’re thinking about solids, use about 6 months as the general starting point and consider your baby’s developmental readiness. [1] The age is a useful guide, not a reason to rush; babies can differ in when they are ready. [2]
Make the timing decision with support
If you’re unsure how your baby’s development fits with the usual timing, bring that question to your baby’s health care professional. [2] You might ask at a routine visit, “Does my baby seem ready to start around 6 months?” or mention a specific concern you’ve noticed. That gives you a chance to talk through your baby’s individual needs rather than relying on a calendar alone.
You can also write down questions as they come up, such as whether a health or developmental concern could affect the timing. A health care professional can help you decide what applies to your baby. [2] If you don’t have questions right now, you can keep the general timing in mind and revisit it as your baby gets closer to that age.
For this decision, focus on when to begin, rather than feeling you need to choose particular foods or a feeding approach in advance. If a question comes up about those next steps, save it for a separate conversation so you can keep the timing decision clear.
A simple timing rule to remember
About 6 months is the usual time to start solid foods, and you should not begin before 4 months. [1]
Think of that timing as a simple guide, not a reason to rush. If you are preparing for the transition, note any questions you want to discuss at your baby’s next visit—for example, whether your baby seems ready around the usual starting age. Your health care professional can help you consider your baby’s circumstances and decide what to do next.
