Abstract: A neonatal cranial support bonnet is configured to prevent a premature child's head from deforming under the force of its own weight, because of underdeveloped cranial plates. The bonnet includes a thin cotton shell with contoured gel packs inside. The gel packs are configured to distribute weight around the skull and eliminate or reduce high-pressure points so as to maintain proper shape of the cranium. The bonnet is also configured to not interfere with development, and to not obstruct airways for breathing, so as to meet current Sudden Infant Death Syndrome prevention guidelines.
