Interesting, I teach two boys piano, they are just over a year apart in age 8 and 9 and they are like chalk and cheese, one really serious and intense the younger doesn't focus at all. Their Mum was almost apologetic for her younger son, I said don't be, it's up to me as an educator to make sure I teach him in a way he will respond to. He doesn't have to be the same as his brother. Do any other mums have any tips on how to handle siblings like this when they're very close in age so we can avoid comparing them so much?
