Wow, thanks everyone for your replies!
I think I'm possibly overthinking it, but I know my 2 year old is a clever little cookie and I so I wanted to get the story straight for future reference 
It would be so much easier if every family did the same!
Contrary to one comment, yes, I'm English, born and bred. I've never heard of Santa only bringing stockings until now! Sure none of my friends ever had this either. My DH (from the South, I'm Northern) hasn't either and we were both pretty much told the same story by our separate families as kids.
To clarify, we give all presents from 'the giver', so no one is giving presents without getting the credit or thanks for it. All presents that arrive on Christmas day are from Mummy and Daddy etc, with the exception of maybe one or two (from us) coming from Santa himself. Includes all presents in the sack and stocking. How we were told as kids was that mummy and Daddy buy the presents but then they go to Santa to be 'checked' and then delivered back on xmas day. This is the bit I was unhappy with really! Both myself and DH were told this as kids. But the story is questionable. It does however, I suppose, cater for the fact that no, we can't afford to buy you xxxxx for Christmas, as Santa isnt the one paying 
We were then told that all our presents that came from grandparents etc, Santa had left those at their houses to be passed on to us, but we still understood that they were being given by that family member etc, not Santa. I don't remember ever questioning this story as a child, but I wanted to get the story straight for my kids!
My query today came from my kids receiving grandparents' gifts a few days early, so I wasn't sure what to tell the kids. "Oh, Santa dropped them off early", or, "they still have to go to Santa to be checked then redelivered"?!
Adults gifts were a grey area for me; whether they were delivered by Santa or not. And I wasn't sure how to explain going Christmas shopping for gifts to give to others, other than using the "they all go to Santa for checking" story.
My kids, and I think it's important, will always know who bought them what gift; Santa is just the delivery guy really.
There's been some great comments and suggestions here that I'll remember. Very insightful. We'll get our story straight for next year, as I think that's when the questions will come.
I've not got on the Naughty Elf bandwagon - to be honest I don't see the point in it, other than a bit of fun I suppose - or the Christmas Eve Box (wait, what?! Kids get presents BEFORE Christmas Day now too?!?!?!).
I really will take on board the comment re using Santa as a behavioral strategy though, as this was pushed on us as kids and I really don't want to ruin the magic. Also, kids will probably still get presents whether they've been naughty or nice anyway, so it would only reinforce their behaviour, even if it was bad behaviour? I can think of at least one little guy who shouldn't get presents based on this premise, but he will do, regardless 
Oh, I wish everyone gave the same story. There should be a instructional handbook!
Thanks again! And Merry Christmas to all!
