Disable the form when you open the new one and re-enable on the form closed event of the child form

Wherever you are opening the child form:...

{
   ChildForm f = new ChildForm();
   f.FormClosed += F_FormClosed;
   f.Show();
   this.Enabled = false;
}

and

private void F_FormClosed(object sender, FormClosedEventArgs e)
{
    this.Enabled = true;
}

How about this?

this.MdiParent.MdiChildren[0].Enabled = false;
