9 month old Pill taste

Alexis

So we have iron pills in our bandaid box, my son had brought them to me and i didn't know a pill fell out i forgot they were in there. Well my 9 month old had red stuff coming out his mouth and i thought he was bleeding but it was the ferrous sulfate red iron pill. Still have basically the whole pill i think he tasted how nasty it was and spit it out. But the coloring went in his mouth and he also spit some out. What should i do? Is that bad 😭
