A toddler won't make 5% of the population sick when in an enclosed air system like a plane, some to the point of needing an adrenaline injection or they will die of anaphylactic shock, or a beta antagonist inhaler for an asthmatic attack (which can also be lethal, although less often than anaphylaxis since it can usually be managed with an inhaler). The rules are not there for pain in the butt. They are there to protect a lot of other people.
