Baby boy has dark circles under his eyes!

Hi all! My 6.5 month old son seems to have really dark circles under his eyes, I’m wondering if this is a sign of a deficiency and if you have any tips for what I can do to help him? I know in grown ups dark circles can be anemia and to increase available iron, but really not sure in a 6 month old. He’s EBF, I haven’t started to wean at all yet and when I do I’ll be following the GAPS method. Thanks!
