Dear Dr. 3months before, i have observed that my baby(2year old) while walking, he used to lift his foot and I thought he is enjoying like that.... later he is continuing the same and I have seen his foot and found that some of thick skin with white dot at centre and whenever i am touching that part he felt pain and not allowing me to do again .. It is looks like Corns and calluses but I am not sure whether I am right or not...pls explain why it is created for him? Cloud you please suggest some medicine for this?..in future, it will come again? Attached images of my son foot along with particular part. Appreciate and thank you for the quick responses
