Starting solids is a major milestone, and one of the more gut-relevant decisions you'll make in your baby's first year, building on what happened well before this point, covered in what your baby's first bites mean for their gut. Most babies are ready somewhere around six months, once the gut lining and digestive enzymes have matured enough to handle food beyond milk or formula. Watch for the readiness signs too: sitting with minimal support, good head control, and real interest in what's on your plate.
Purees and baby-led weaning both work well for gut health. Purees make it simple to offer a wide range of vegetables and fruits in the first weeks. Baby-led weaning, where your baby feeds themselves soft finger foods, brings in more texture and flavor sooner. Neither method has an edge for gut health specifically. What counts is variety, rotating through different foods rather than relying on the same three or four safe ones for months at a time. If you're introducing solids to more than one baby at once, twins, triplets, and beyond covers how that variety goal holds up with multiples, and cooking for a family with different gut needs can help once a baby's plate starts overlapping with everyone else's.
Allergen advice has changed substantially over the past decade. Doctors used to recommend delaying peanut, egg, and other common allergens until toddlerhood. Current guidance from the CDC and American Academy of Pediatrics says the opposite: introduce potentially allergenic foods, including peanut, egg, dairy, wheat, soy, fish, and sesame, around the same time as other solids, in age-appropriate forms.[1] Research now links early, regular exposure to lower rates of food allergy, not higher.[2] If your baby has severe eczema or an existing egg allergy, talk to your pediatrician before introducing peanut, since they may want to test for a peanut allergy first.
Iron needs jump around six months, right as a baby's birth iron stores start running low. Meat, lentils, beans, and iron-fortified infant cereal are good early choices. Pairing them with a vitamin-C-rich food, like a few slices of orange or steamed broccoli, helps your baby absorb the iron better.
A rough timeline
Good first foods to start with
- Iron-fortified infant cereal or pureed meat
- Mashed lentils, beans, or lentil dal
- Thinned peanut butter mixed into puree or breast milk
- Well-cooked, mashed scrambled egg
- Plain whole-milk yogurt
- Soft-cooked vegetables: sweet potato, carrot, broccoli
- Ripe, soft fruit: banana, avocado, pear
- Hives or a raised, red rash appearing soon after eating
- Swelling of the lips, face, or eyes
- Vomiting shortly after a new food
- Wheezing, coughing, or trouble breathing
- Sudden paleness, floppiness, or unusual sleepiness
You don't need a new food every day. One new food every two to three days is plenty, and you can keep offering foods your baby already likes alongside it. Keep a simple running list of what you've tried: it's a handy way to spot gaps, like realizing you've offered the same five foods for two weeks straight.
What to do with this
A food your baby turns down once can go back on the menu later; a scrunched-up face at a first bite is usually about unfamiliar texture, not a lasting dislike. Keep offering variety on a relaxed schedule and let repeat exposure do the work.
