Weaning - allergens?

Personally I still would because if she chooses to not be a vegan/vegetarian etc then at least you'll know that she's safe eating those foods

If you and your partner have been vegan 10 years that means you both had a lifetime of exposure to non-vegan products before you made the choice to switch over. Speaking as a child who grew up with allergies to so many different foods, please introduce all the top allergens to your child now. I understand the ethical considerations but also consider that even if they choose to be vegan/vegetarian in the long run, there is potential for exposure to cross contamination. they could have a life threatening reaction if they’re allergic to something. Allergies are so annoying and sometimes deadly. Research supports early introduction (but also OFTEN introduction). So it’s a hard one, I see why you’re asking the question. But this is the prime time if you want to do it for health benefits.

Been vegan for 15+ years now, I am feeding my little one a veggie diet (and have given her fish + shrimp once each) to keep dairy allergen in check just in case.

I think for children who are likely to try someone's birthday cake / ice cream / cheese sandwich etc... I'd rather be prepared :)

From 1 we'll be vegan at home and veggie / flexi (her only) outside.

Thanks all!

Everyone can develop an allergy at any point during their life time. Introducing dairy/fish/eggs once doesn't mean they won't develop an allergy in the future. Personally, I chose not to introduce animal products to my little one. Whatever you choose, will be the right choice for your family.
