What I do is make a form with a large number of blanks (order form,
children stats), and then in validation determine which ones are
filled in.

Now if you want to edit it, you bring the data back in a session array
(to determine change) and an array for the POST form. When validation
is good you compare the POSTed data to the session data and do what
changes are necessary.

This process bypasses the (enter number here) thing as well as the
confusion in trying to add more child elements at a later time.
