In your child form, you're probably defining your child type with a name like 
"TMDIChild".
To use the methods of that type from your main form, try something like this 
example (from a program of mine)...
  procedure TMainForm.Save1Click(Sender: TObject);
  begin
    if ActiveMDIChild  nil then
    with TMDIChild(ActiveMDIChild) do begin
      if Pos('NONAME', Editor1.FileName) = 1 then
        SaveAs1Click(Self)
      else
        Editor1.SaveToFile(Editor1.FileName);
    end;
  end;
The "with TMDIChild(ActiveMDIChild) do" portion is almost certainly what you 
need.
