Complementary Feeding: A Guide to Starting Solids

There comes a moment when milk alone isn't enough anymore and your baby starts eyeing your plate with curiosity. That's the start of one of the loveliest (and most question-filled) stages of parenting: complementary feeding, the shift from milk only to tasting real food for the first time.

Before we go further, the most important thing: this is a general guidance to support you, and it is in no way a substitute for your pediatrician's advice. Every baby is different, and your pediatrician knows your child's specific situation: weight, development, allergy history. Use this to walk into your appointment with better questions, not to replace it. With that clear, let's get into what you can start learning.

When to start? The signs of readiness

The general recommendation is to start around 6 months, keeping milk (breast milk or formula) as the main food throughout the first year. But age is only part of it: what really matters are the developmental signs. Your baby is probably ready when they:

• Sit with little or no support and hold their head steady.
• Have lost the tongue-thrust reflex (early on they pushed any solid right back out).
• Show real interest in food: they reach out, open their mouth, follow your bite with their eyes.
• Bring things to their mouth with coordination.

If your baby is 6 months old but still can't sit up, wait a bit and check in with your pediatrician. There's no rush: milk still covers the essentials. Starting too early doesn't help and can upset digestion.

A calming tip: in the first days, food is for exploring, not for filling up. If most of it ends up smeared on their face and bib, you're doing great. Eating is learned through play.

First foods and textures

There's no single "correct first food"; what matters is offering nutritious, simple, well-prepared food. Some gentle, easy options to start with:

• Cooked, mashed vegetables: zucchini, carrot, chayote, sweet potato, potato.
• Ripe fruit: mashed banana, avocado, papaya, cooked apple or pear.
• Grains: well-cooked oatmeal, soft rice.
• Iron sources, key at this age: well-cooked egg yolk, strained beans, finely ground meat or chicken. Iron is one of the most important things at this stage.

For textures, progress alongside your pediatrician based on your baby:

• To start: smooth purées and lump-free mashes.
• Next: chunkier mashes, soft foods in pieces they can grab (banana, cooked zucchini in sticks).
• Later on: small pieces of the family meal, finely chopped and soft.

Introduce one new food at a time and wait two or three days before the next one. That way, if something doesn't agree with them or triggers a reaction, you know what caused it. Offer without pressure: if they refuse something, try again another day. Just like with older kids, accepting a new flavor takes several tries, so patience with new foods starts in babyhood.

Introducing allergens: what changed

Allergenic foods used to be delayed. Today the general guidance is the opposite: introducing them relatively early, within this stage, may help reduce the risk of allergies, unless your baby has a history that rules it out. This should always have your pediatrician's sign-off, especially if there are allergies in the family.

Common allergens include egg, peanut and other tree nuts (always as a smooth butter or finely ground, never whole because of the choking risk), wheat, fish, dairy and soy. The general safe approach:

• Offer them one at a time, at home and early in the day, so you can watch.
• Start with a small amount and monitor for reactions (hives, swelling, vomiting, difficulty breathing).
• At any sign of a reaction, stop and seek medical care.

I'll say it again: this point in particular is worth discussing with your pediatrician before you begin.

What to avoid during the first year

Some foods just aren't ready yet, and here there's no gray area:

• Honey before age one: risk of infant botulism. This is absolute, not even a taste.
• Salt: a baby's kidneys are immature. Food goes without added salt.
• Sugar and sweeteners: no sugary juices, desserts or soda. They don't need it and it spoils the palate.
• Cow's milk as a main drink before age one (it's fine in recipes, just not as a drink).
• Choking hazards: whole grapes and hot dogs, whole nuts, popcorn, hard and large chunks. Everything cut small and soft.

Having no salt or sugar doesn't mean it's bland to them: your baby is discovering natural flavors for the first time and enjoys them just as they are. In fact, this is the best moment to lay down good eating habits for the family, because their palate is forming from scratch.

Do it as a family, without the stress

Whenever you can, let your baby eat at the family's mealtime, in their chair, watching you eat. They learn by imitation, and the table becomes a social place from an early age. Let them touch, smear and explore: the mess is part of learning, not a problem.

And breathe: there will be days when they eat eagerly and days when they just play with their food. As long as milk stays the foundation during the first year, solids are practice and discovery. You're planting their relationship with food for life.

Complementary feeding is a journey of trial, patience and a whole lot of love. A tool like Provecho can help you plan and vary meals for the whole family, including gentle, nutritious ideas to go alongside this stage of your baby's. And remember: bring your questions to every appointment with your pediatrician, who is the best person to guide you with your little one.

Start calmly: one cooked, mashed vegetable, no salt, at family mealtime. That first bite is the beginning of something wonderful.
