Happy Birthday, My Lovely Nephew

It's my nephew's 10th Birthday today, Aug. 15. The other day, I was thinking of a gift that we can give to him, but I have no idea what to give. I told my sister to buy a toy or some clothes that he can use for school so he will be happy.
He is the first grand kids of my parents and my first nephew. Though he's the first grandchildren of the family, we treated all of them fairly so there will be no jealousy.
