So here’s what I know about this book – it is not a recent publication. I read about it a long time ago – maybe in a book review, and the review got tossed and I have wanted to find it for a while.
It is fiction. A first time mother obsessively tries to communicate with her unborn baby/fetus and all day and all night feeds info into her belly – music, news, stories, but the baby concludes this is not a world in which it wants to be born. And the struggle begins to get the baby to be born by then telling it why.
Something along those lines.
Any chance it’s Baby, Come Out! by Fran Manushkin and illustrated by Ronald Himler (1972)?
Quite popular, I believe, despite being out of print. Manushkin is in her 70s and wrote dozens of books, inlcuing the Katie Woo series – check out her website!
