So my one year old child caused his face to swell in order to get noticed? This is the kind of thing that makes no sense.
No, but it’s far more likely that you, naturally protective of your own child, overestimated the severity of the reaction (if there was any). I say that because the most logical answer is that the mechanical properties of peanut butter coupled with the general inability of infants to do anything are far more likely to cause choking and red-faced swelling than an extremely rare life-threatening allergy.
Quit slapping him.
