I'm sure they will! I'm sure you have traditions that you did every year and that's what they will remember. I couldn't tell you what I got any year except the year I got the cabbage patch doll I had BEGGED for. Whenever we were in the "mall", I always went to the store where they had toys and they had this big huge stack of cabbage patch dolls...that was THE gift that year. And I wanted one SO bad...I wanted one that had a pacifier, so I had picked out the one I wanted...she had red hair in ponytails and she had a pink and white striped shirt and jeans and her name was Jeannie Gabby....I would just go and stare at her...and then one day I was looking, and the lady at the shop came and picked it up and said it had been sold and I was so so so sad...until I opened my present on Christmas Eve. My mom had bought her right in front of me and I hadn't even noticed. And my dad had a new girlfriend that year, and she was very into crafts and she made me a homemade cabbage patch doll, with brown hair and I named her samantha, and then I also got a "flower patch kid"...it was a cabbage patch kid knock off, because cabbage patch dolls ended up being really hard to get, so there was a huge market for anything that could pass as a cabbage patch doll. That's the only gift I remember from all those years because I had begged so hard for it....the rest I couldn't tell you. It was the traditions...the cookies we always made every year, and my mom's famous poppyseed bread recipe that she made as gifts for all her friends, who would hide it from their kids and husbands so they didn't have to share...and people always asked for the recipe and she said when she moved or she died, she'd give it to them....so she asked us to print it in the memorial card when she died.
The point is, whatever traditions you have, those are the things they will remember. Like....the special ornaments that you hang every year, or that they always got new PJs, etc...
