When can babies have wakame?
Can babies have wakame?
Babies can have small amounts of wakame from about 6 months when it is rehydrated, cooked soft and blended into food, with very finely chopped wakame from about 7–8 months. Wakame is a seaweed that is naturally high in iodine, so offer it occasionally rather than daily. Wakame is not a common allergen, but seaweed salads often contain sesame and soy.
How to serve wakame by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Soak dried wakame in water until soft, rinse well, simmer briefly, then blend a small pinch into smooth congee, rice porridge or mashed tofu so no strands are left. Offer it on a spoon.
7–8 months
Chop soft, rinsed wakame very finely and stir a small pinch into rice, congee, soft scrambled egg or mashed tofu. Keep pieces tiny so they do not stick to the roof of the mouth.
9–12 months
Mix finely chopped soft wakame into rice, noodles, omelets or soups. Keep pieces small so they do not stick to the roof of the mouth.
12 months +
Toddlers can have chopped wakame in miso soup made with low-sodium miso, noodle bowls and rice dishes. Keep portions small and occasional.
Why it’s good
Wakame gives babies iodine for thyroid health and brain development, plus folate, magnesium, calcium and fiber. Seaweeds can contain very high amounts of iodine, so a small pinch a few times a week is enough.
Safety notes
- Seaweed is high in iodine, and too much iodine can affect the thyroid. Offer small amounts of wakame occasionally rather than every day.
- Rinse and soak dried wakame well. Some products are packed with salt.
- Large, slippery pieces of seaweed can stick to the roof of the mouth or wrap around the tongue. Chop wakame finely.
- Store-bought seaweed salad is often high in sodium and sugar and contains sesame and soy. Save it for toddlers and offer small tastes.
- Avoid hijiki seaweed, which is high in inorganic arsenic.
A low-allergy food, still worth watching
Wakame is not a common food allergen. Seaweed salads and miso soups often contain sesame, soy or wheat, so introduce those allergens separately first and read labels.
