I'm not sure if I can say 'something from my childhood' just yet lmao, but I do have some things from when I was younger.
I have this little Christmas picture frame I painted when I was in year 1 for school. It has a picture of my class from when I was little in it. I had to change schools in year 5 and that absolutely broke my heart, so I used to find myself looking at the picture a lot. I tend to get really attached to people lol
I also have this little fairy doll I got from my grandfather who passed away a few years ago. It's fairly broken and beat up, and dolls scare the crap out of me, but I love it nonetheless. It just stays out of sight where I can't see it lmao. I think she's still really pretty, even if she's missing a leg <33
Excuse the low quality image
