@ImPrincessAurora That sounds like a lovely tradition you're creating for your DC - I especially love the idea of writing all their achievements in the card. Hope you don't mind if I steal that idea!
OP I think it's very normal for those of us raised in abusive and/or neglectful families to place extra importance on birthdays - but this can often lead to even more disappointment.
As a young child I was generally happy with whatever I got but as I got older and started to have opinions and tastes of my own, it caused immense friction between me and my mother, who would always buy me presents that would have suited the daughter she wanted me to be. So I would get given pink frilly stuff - I was a total tomboy. Or some sort of makeup set, when I actually longed for a Meccano set.
At least my sister also received crappy gifts. She was the girliest girl who ever girled - but my mum would give her stuff like board games or sports stuff (which she hated, she liked playing with dolls) or those awful "It's fun AND educational!!!" toys which were a thinly disguised way to say "You're crap at maths!"
Actually this is the first time I've really thought about it - I'd always just thought she was shit at buying presents, but now I realise it must have been deliberate.
While I was still in contact with her I actually told her not to do gifts at all on my birthday, just a card, because every single year without fail she would ask me what I wanted, and I would reply with something very specific, and she would then give me something that was either completely unrelated or just in a totally different style. Like - I said having moved into a new house with an old fireplace, I would love an old wooden clock like Grandma used to have, to go on the mantelpiece, one which chimes the hour. She bought me a horrible metal one, too small to see from across the room, which didn't chime. And of course I felt obligated to put it on the mantelpiece because what kind of ungrateful child spurns their mother's gift, even if it wasn't what I'd asked for?
Birthdays are a fuck of a lot less stressful now she's out of my life.
