Best first proteins for babies
Protein tends to get overlooked in the rush of purées and fruit, but it is where the iron is, and iron is the nutrient that matters most once solids begin. Here is the spread of great first proteins and how to serve each one.
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
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.
