Best first proteins for babies

Everyone remembers the purées and the fruit. Protein gets forgotten, which is a shame, because it is where the iron is, and iron is the one nutrient your baby’s body actually starts running short on around 6 months. Here is the full spread of great first proteins, and how to make each one soft enough.

Why proteins matter early

Around 6 months, a baby’s iron stores start to run low, and milk alone does not fully replenish them. Many first proteins double as iron sources, which is why they deserve an early spot. Pair them with a vitamin C food (tomato, a little fruit) to boost absorption. See iron-rich first foods.

The best first proteins

Meat & poultry, puréed, minced, or soft strips, the top iron source
Fish, flaked and boneless (low-mercury)
Egg, fully cooked
Beans & lentils, cooked soft and mashed
Tofu, soft cubes
Yogurt & cheese, plain, full-fat
Nut butters, thinned, never a glob

Ready to branch out? Try single proteins like chicken, turkey, salmon, trout, lentils, chickpeas, and black beans.

Mind the allergens

Several first proteins, egg, fish, shellfish, soy, dairy, and nuts, are common allergens. Introduce them early (that is the current advice), but one new one at a time, watched for a few days. See introducing allergens.

Keep it soft

Moisture is everything: mince meat with its juices, mash beans, flake fish, mash or scramble egg, cube soft tofu. See how to cut food safely.

Frequently asked questions

What are the best first proteins for babies?

A varied set works well from around 6 months: well-cooked meat and poultry, fish, egg, beans and lentils, tofu, and dairy like yogurt and cheese. Nut butters (thinned) count too. Aim for variety across the week, and lean on the iron-rich options, since iron is the nutrient that matters most at this stage.

Why is protein (and iron) important at 6 months?

Around 6 months a baby’s built-in iron stores start to run low, and breast milk alone does not fully top them back up, so iron-rich foods become a priority. Many first proteins (red meat, beans, lentils, egg yolk) are also good iron sources, which is why they earn an early place on the plate.

Do first proteins need special allergen care?

Several of them are common allergens: egg, fish, shellfish, soy (tofu, edamame), dairy, and nuts. That is not a reason to avoid them, current advice is to introduce allergens early, but do introduce each new one on its own and watch it for a few days so any reaction is easy to trace.

How do I make proteins soft enough?

Keep everything moist and soft. Purée or mince meat with its juices, mash beans and lentils, flake fish (bones removed), scramble or mash egg, cube soft tofu, and stir nut butter in thinly. Pair iron-rich proteins with a vitamin C food to help absorption.
