A young girl is adjusting to life with her new baby brother. “[T]he good ol’ days are over,” sings the repeated refrain, “It’s official, it’s the news! / With my brand-new baby brother / came the brand-new baby blues!” Appelt’s catchy, child-friendly text and Murphy’s energetic, engaging pictures illustrate her woes, from the golden memories of her days as the only one to her mother’s newfound busyness, her father’s goofy attempts at entertaining the baby and the unfortunate fragrance of stinky diapers. Funny and concise, the rollicking rhyme bounces along, accepting the frustration natural to the situation, while gently allowing the girl’s love of and appreciation for her brother, as well as her anticipation of a future playmate, to gradually shine through. The process is complemented by the illustrations, which modulate in palette from angry blues and greens to sunny yellows, while serene compositions replace off-kilter ones. Older brothers and sisters will easily identify with this jaunty heroine and profit from her realizations—an excellent choice for a new older sibling. (Picture book. 3-6)
