3-7yr Kids Book Recommendations?

TL;DR: Got any of them "banned" book recommendations for kids? We have a 2 1/2yr old and a 6 yr old who love book time

So a recent popular post in politics was about a book that stirred up controversy - My Shadow is Purple, which is the second book in a series (Here's the first).

Local library doesn't have them unfortunately, so I'll be putting in a request (then checking out a local store).

It made me wonder about some other great books out there that more conservative areas might not have. My township is pretty progressive (, but not large, so the school library is only OK. The county library is literally a few blocks away, so no town library. And while amazing as a library, the in-county magas have made the library slow down on some kinds of books. Its ridiculous, but one problem at a time.

So I'm hoping to get some kids books they might not otherwise see, like the My Shadow is Pink/Purple books mentioned, but I don't know what's out there.

Anyone have some favorites to share for the young kids? Looking forward to any ideas!
