They typically target infants through early tweens. Suggested ages range roughly from 0 to 12 years, with many titles aimed at about 2–8 years or 3–12 years.
Most are published in standard children's formats—primarily hardcover and paperback editions.
Many use a roughly square 8.5" x 8.5" format; some are wider, for example an 11.0" x 8.5" paperback size.
They use varied approaches—gentle bedtime-style prose, alphabet explorations of NICU terms, and sibling 'tour'-style narratives that explain the NICU to young children.
They also speak to siblings, former preemies, and NICU staff, offering explanations and perspectives tailored to each group.
