Bambas are recommended in the U.S. as well, but our kid entered anaphylaxis after eating just 5 bambas his first time, at about 6 months of age. It's certainly possible to have a peanut allergy despite early exposure. Recommendation in the U.S. is now for pregnant women to eat peanuts to expose the fetus in utero, but even this doesn't always work.

Kid is desensitized now after a year of oral immunotherapy, so add us to the chorus of voices saying "It works", but it can strike early and severely despite the parents' best efforts.

It's not just about early exposure to allergens, it's also early exposure to pathogens. There's a growing body of research that constant disinfection of hands and surfaces is what really caused the allergy outbreak. Humans need to prime their immune systems with exposure to pathogenic bacteria at an early age so that it can learn to fight them and not other substances which leads to allergies.

> it's also early exposure to pathogens

Careful, that's not really been proven. There's an enormously important difference between these two theories:

1. The individual human immune system needs to be calibrated by wider exposure to... actual pathogens.

2. The individual human immune system needs to be calibrated by wider exposure to... benign bacteria that we've co-evolved with. ("Old friends" [0].)

Those involve very different plan of treatment and associated risks, and there's no guarantee the riskier one will give better results.
