This is a hereditary condition called scrotal tongue or fissured tongue. It is more common in children with Down's syndrome but I assume that your child does ot have this syndrome. It usually persists throughout life. There is no pain or discomfort but certain foods such as spices may cause a burning feeling that is more marked than usual. It is important to keep the tongue clean by brushing the tongue gently with a tooth brush. This condition is not due to a vitamin deficiency.
