Book excerpt: \"Shireen's latest gem ought to come on prescription\" The Observer's Best Children's Books of 2021. Barbara is having one of those days. She has a sock problem and there's a strange pea. Then, all of a sudden, Barbara's Wobbler is out of control! But what happens when a bad mood like this comes along? Barbara has a lot to learn about the ways of wobblers in this laugh-out-loud story from Nadia Shireen. A brilliantly funny and sensitive way to understand and deal with tantrums. \"These are the most brilliant, beautiful and silly picture-books out there at the moment. Little doorways of joy.\" Caitlin Moran
