Besides a lot of the classic children's books (goodnight moon and stuff) I'm looking to get some left leaning children's books. Stuff with like a pro-union/anti-capitalist/anti-fascist slant. I'm also queer so LGBTQ children's books recommendations would be welcome, I didn't have anything like that when I was growing up and I probably would have appreciated it.
Farmer Duck and Click Clack Moo are pretty great. While not exactly political, we're pretty big fans of the ¡Vamos! books over here - think Busytown, but without the dated 1960s ideology baked in.
Thanks for the recommendations, getting some Spanish books is a great idea too!
