  The other option I'm considering is using the Related Items feature as each attachment relates to an item.

  http://formsdesigner.blogspot.com/2013/08/how-to-create-forms-with-related-items.html

  I was reading this article and I just want to confirm with you...

  Can I pass the current item's id into a field in another list (child)... and thus cause the new item to be related to the parent?

  The related items section on the parent form would always be empty until a new item was created which linked the two via a field in the child called Parent_ID with the parent item's ID field.

  Hopefully I'm explaining that in a clear way.  I'd want to add related items and associate them with the current parent item by default.

  [#1]: Hi,

  Yes, you can use the Related items control. In the post you've mentioned above, I described how to prepopulate a lookup field in a child form via JavaScipt. Please, note that you cannot use related items in a new form because the parent item is not created yet.

  You can still use the attachments field and I can provide you with code that checks whether the user has added a particular number of attachments.

  [#2]: Yes - I came across that issue.

  I think it's better for my scenario that I get a count of the number of attachments.  What do you suggest?

  [#3]: Please, place the following code into JS-editor.

  fd.onsubmit(function() {
  	if ($('#idAttachmentsTable tr').length < 2) {
  		alert('Please, add at least two attachments');
  		return false;
  	}
  	
  	return true;
  });
  

  It checks whether the current user has added at least two attachments before the submission.

  [#4]: Hi Dmitry,

  Works great.  Thank you.

  How about getting a count of the number of related items for a similar purpose?  I know this question will come up as I add related items to my form.

  [#5]: Hi,

  It depends on the rendering mode of the related items. Please, specify which one do you use: server or client side?

  [#6]: Not sure yet.  I am just adding it in this morning.  Could you mention both ways?

  [#7]: Please, assign a CSS class to the related items control in Forms Designer e.g. related-items. Next, insert the following code into JS-editor:

  fd.onsubmit(function() {
  	if ($('.related-items .ms-listviewtable > tbody > tr').length < 2) {
  		alert('Please, add at least two attachments');
  		return false;
  	}
  	
  	return true;
  });
