A. First you have to see what is the difference between two kids and then you have to tell your kids it is okay to fight there is no problem because you cannot stop them from fighting so you can say that okay it’s okay that you’re fighting but you cannot touch each other there should be no physical fight and then second would be at whatever it is between you nobody is going to come to me and say take my side you know you have to sort your and resolve your problems on your own of course do keep an eye on that but don’t interfere and tell them from the beginning itself it’s okay if you fight but always remember at the end of the day you are going to be there for each other nobody else from the beginning itself if you try to teach the kids that they are best friends they are always going to be there for each other new person is going to come then slowly you will see that they will learn to stand through thick and then with each other even if they fight because these things we cannot stop but we can show them the correct way to handle the situation
