As science now knows, young babies exposed to a bigger variety of pathogens will have greater tolerance when they grow up. It would be good if new mothers were given information on the latest science about this. For example if the science support it, when infants are 6 months of age their mothers could be texted a reminder that feeding their child a crumb of peanut will likely reduce their chances of having a peanut allergy later in life. If they want that reminder, that is. It is a ffree world, but the more information young mothers are given, the better.
