First, your form are not child and parent to each other (unless they are MDI parent and MDI child). Child-parent relationship is made defunct for forms.

There is no special solution for this "problem". You simply need to use the property Location and Size for both form and set location of one form the way it is placed in the middle of another one. (But why would you hide a part of one form behind another one? are you sure this would be acceptable UI design?)

Technically the second form should be a progress dialog[^].

For show form center to its Parent window

set the start postion for child window.

private void OpenForm(Form parent)
{
    FormLoading frm = new FormLoading();
    frm.Parent = parent;
    frm.StartPosition = FormStartPosition.CenterParent;
    frm.ShowDialog();
}
