Hi, I have noticed that my 4 year old son has a dark/black flat spot on his lower inner lip (just at the middle where the top and bottom lip meet when closed.) It seem to appear suddenly and has been there for over a week. I noticed this earlier in the year but it went await without me realising when it did. Does not cause any discomfort and he behave normal. Do you have any idea what it might be.
