My 20-month-old son got a tiny sip of a black coffee drink (no milk or other ingredients added) and almost needed his EpiPen
Jr before his reaction stopped progressing on its own. His face, back, and
chest got littered in hives, even his eyelids. His eyes got all red and itchy, and his nose started running off his face, which induced some sneezing and coughing. He then acted very cranky and off, and even felt fevered, for the next two days.
