My 2 year old son got a hold of a sharpie permanent marker, Despite the obvious Marker on everything, he also appears to have gotten it in his mouth(according to the calligraphy on his tongue) and even though he seems to be fine( acting normally) should I be concerned?
Welcome to the ChatDoctorInks contain dyes, some alcohols and a chemical called glycol or glycol ether.  Glycol and glycol ethers can be toxic in larger amounts, but the quantity in a pen or marker is very small, to the point of being insignificant. The main issue is usually the cosmetic staining of the skin or tongue, which may last for several days.  Ink can also cause mild stomach upset rarely. So don't worry.
