Close the second child form if one form is already open

I have created windows application in which there is a parent form with many child forms. Now what I want to do is, Close the second form if first form is opened. I have menustrip control, that is disabled once any form is opened and enabled if form is closed. Now I have added shortcut keys in menu strip for opening the forms. By using the shortcut I open the first form, then again by using shortcut, the second form is opened and the first form is closed instead of second form.
 The code I wrote :-
 
void MDIParent1_MdiChildActivate(object sender, EventArgs e)
{
      if (this.MdiChildren.Count() > 1)
         {
                     foreach (Form childForm in this.MdiChildren)
                     {                                                     
                                 if (childForm != this.ActiveMdiChild)
                                 {
                                          childForm.Close();
                                          return;
                                  }
                     }
            }
}
 
 
Thanks in Advance !!!!
