       | Generate a miasma of benign pestilence in your child's crib,
       | mimicking the protective inoculations provided by early exposure
       | to peanuts and other potential allergens, "farm" air, and the
       | like. It could be packaged with Flonase for sneezing parents and
       | an 'essential oils' scent dispenser to cover the barnyard smell.
       | 
       | Use AI to tailor the precise blend of aerosolized rodent feces
       | and tree nut dust to optimize your child's immune system, and et
       | voila: funding!

         | not long after starting solid food.)
