If it's the blog for the whole project, then you should not worr

1. If there are more people involved other than your son and the Indian kid, other people would know. Trust me, people do recognize your talent and work.
2. Worst case scenario, if he ended up taking all the credits, THEN your son would hurt, THEN he will think, THEN he will learn. Don't you wish you had this "to learn it the hard way" when u were in high school? We all have to learn it the hard way many times in our life, this would be a great start:)

Turn negativity into positivity:)
