Abstract: A new and improved blanket apparatus for fitting over a baby seat or carrier which has a top and sides includes a flexible cloth member having dimensions sufficient to fit over the top and sides of the baby seat or carrier. The flexible cloth member has an outer edge; and an elastic strip or a draw string is installed near the outer edge of the flexible cloth member, for gathering the outer edge to form an opening having a plurality of adjustable sizes. A first adjustable size of the opening is sufficiently large to fit over the top and sides of the baby seat or carrier for installing the blanket apparatus on the baby seat or carrier. A second adjustable size of the opening is sufficiently small to resin the blanket apparatus on the baby seat or carrier, by preventing the blanket apparatus from slipping over the sides once the blanket apparatus has been installed.
