In this gorgeously illustrated board book, a toddler describes life with her ill mother, who gently floats in a bubble on almost every page. Castrée’s delicate, detailed artwork, in warm, rich colors, reveals charming details of day-to-day life that carry on around, and occasionally in, Maman’s bubble. Clearly rendered facial expressions, from the mother’s concern, sadness, and enduring love for her daughter to the daughter’s blithe playfulness, make the emotional turns unmistakable. The imagery of the mother, isolated but not totally cut off from her child, is a very useful tool for talking about illness: the daughter is free to enter the bubble, but it keeps Maman from doing many things, like going outside. Though the subject matter is tough, this thoughtfully written book, which ends on a hopeful note despite Castrée’s death in 2016, might be just right to share with little ones struggling to come to terms with a parent’s infirmity.
