It is indeed a lovely book. Rachel Rooney was treated horrendously when, as PPs have said, her book carries messages of body positivity and inclusion that are perfect for the age group.
i don’t really get the aggro here
Indeed.
so put them all on the shelf right? We’re not in the business of banning books?
This comment is an interesting one to drop here. There's a difference between banning books (a phrase which evokes an image of book burning etc in the Nazi era) and schools or other libraries choosing which books to stock based on which are appropriate for children. It's a curiously emotive phrase to drop in to this thread.
There have been several threads about books which are inappropriate for preschoolers, because of how they set the scene for children thinking that their bodies aren't the right ones for them. Here are some:
This thread is about Grandpa's Pride, a book which teaches the same age group about bondage gear and double mastectomies, through its illustrations.

This thread is about the Proud Trust resources, which include a book called Alien Nation. In this book, everyone lives on the blue or pink planet, named Planet Boy and Planet Girl respectively. It starts well, challenging the stereotypes that happen on each planet... and by the end everyone is encouraged to choose their planet themselves, when they're ready, based on which stereotypes match them best.

Obviously the discussion of choosing appropriate books, and highlighting why other books aren't appropriate (not "book banning") is relevant to this thread as well. It wouldn't be "aggro" to be appalled at the large number of books which have made it on to preschool, primary and secondary school reading lists where the messages are woven in to the words and illustrations to encourage children to question whether their body is the "right body" for them.
Now that the Cass Report has been released and reasonably widely publicised, it opens up more opportunity for preschools, nurseries, schools and Local Authorities to have more open discussions about which books provide positive messages about this topic and which don't. Hopefully authors and others in publishing who speak out against it will create a Streisand Effect in the conversation.
