Abstract: An infant's bedding article that reduces the occurrence of SIDS, where the article has a fitted sheet for a mattress and a partially fitted covering that is connected to the fitted sheet. The partially fitted covering has an infant size covering panel with an opening top edge, a fitted bottom edge, a fitted side edge, a partially fitted opposing side edge, and an extension panel. The extension panel is coextending from the infant size covering panel. The extension panel extends beyond the partially fitted opposing side edge, and the extension panel is not fitted, and therefore it enables the opening top edge to be turned down when laying the baby on their back on the mattress. The extension panel is sufficiently long that it can be tucked under the mattress. The fitted sheet and the partially fitted covering are joined where the sheet and covering are fitted.
