In this board book told in sweet rhyming couplets, we are invited to celebrate a new baby, and their gender-neutral pronouns, from the point of view of their excited siblings. The baby is snuggly and sweet in their bright pajamas, they love to snooze and sway...and when asked if they're a boy or a girl, we're told, "We aren't sure of their gender yet--and they bring us so much joy." Accompanied by delightful photos of babies and siblings of diverse ethnicities, it's clear that no matter which gender pronouns baby eventually chooses, they are loved just for who they are, and always will be.
