Hi georgie123! I actually have seven siblings (quite a few, I know!): five brothers and two sisters. I’m the youngest of all of them. And actually, out of all of them, I’m the only scientist! I’m not sure exactly how that came about, neither of my parents are scientists, but my grandma studied biology at university. So maybe I got it from her.
Having lots of siblings is good fun, makes for busy Christmas celebrations, for sure!
