My DH and I are childfree not by choice. It has been a journey to accept this but it's probably best in the long run for us (health issues etc).
My DM died a couple of years ago. When she was alive, I would receive birthday and Xmas presents from her and my two closest aunties. They did the same for my DH. Now she's passed away they don't even send a birthday card even though they know when it is. I suppose my DM had been reminding them but it was a shock to go from a few cards and presents to none at all. It's odd to me because we are still in touch and they visit sometimes and check in, and supported me during the bereavement. My DF also died over a decade ago.
We have always sent birthday cards and presents, more recently just cards unless a big birthday. My aunties buy presents for their children and grandchildren, I think one of them assumed we would eventually have a child, but since we aren't she has seemed less and less interested in our lives.
On DH's side we have a nephew but have recently fallen out with SIL (she said some awful things to us regarding my health issues) so we are just sending presents for nephew this Xmas. DH is no contact with his dad for similar reasons and past emotional abuse. His mother died a few years ago. SIL would often forget my birthday or promise presents which never arrived. They usually did Xmas presents though.
AIBU to be sad that our only presents will be from each other this year and probably always now? We do have childfree friends but they are bad at gifts and cards and I don't like to assume that people can afford it. I don't get birthday cards or anything from friends either. The only time I have was when my DH reminded some people and they sent things because I had had a rough year.
We have a neighbour with young children who we get along with and they have very little family around, so we get them a present each too, but never anything in return.
I suppose it's a silly question because I'm not giving just to receive, or I would have stopped ages ago. I like to get in the spirit of the season, but it would just be nice to have a card or something from others occasionally. I think people forget that people without children can feel a little empty at Xmas.
