There's nothing more frustrating than spending hours composing a heartfelt letter to Santa, finding a stamp, carefully addressing it and popping it in the postbox, only to never hear from him.
It happened to us all as kids, year after year. You were left wondering if he'd even received your list, or whether your repeated requests for a Mr Frosty were just getting lost in the post.
Okay, so we know Santa's pretty busy around Christmas time but, still, the man was a pretty poor correspondent. Doesn't he have elves for this kind of thing?
However, kids today will never have to know the disappointment of never getting a reply to their letters, because the Royal Mail now offers a service that promises anyone who sends a letter to Santa (carefully following the instructions provided on their website) a personalised reply from the man himself.

All it costs is the price of a stamp.
Here's how to get a reply from Father Christmas:
Step 1: Write your letter - it's up to you what you want to include, but we recommend your Christmas wishlist, along with reasons why you've been very good this year.
Step 2: Ensure you include your name and full address on your letter, so Santa can write back to you.
Step 3: Pop it in a stamped envelope, addressed to:
Step 4: This one's important - you need to send your letters by Friday 9th December, so Santa has a chance to reply before the Christmas rush. Otherwise, the Royal Mail can't guarantee a reply.
Santa is also joining forces with the Royal National Institute of Blind People (RNIB) again this year to ensure blind and partially sighted children also get a reply to their festive letters - in their preferred reading formats, be that braille, audio or large print. Parents can find out more via the RNIB website.
Finally, the Royal Mail have passed on this message to all kids from Santa himself: "Looking forward to delivering your presents on Christmas Eve. Make sure you remember my mince pie and Rudolph's carrot!"
He does love a mince pie.
