My youngest two have a few blue veins noticeable on their faces, especially round their eyes. ToddlerMe also has ones similar to your picture, but actually just looking now and they aren’t as prominent as they were previously. They aren’t an issue at all, in my experienceDoes anyones little ones have a small visible purple/blue vein on their cheeks? Should I be worried? It’s not as noticeable as it looks in the pictures
