Abstract: A wrap for young infants (FIG. 3) that keeps them warm while allowing free movement of their limbs and bodies. The main middle section of the wrap (10) has a shape of an elongated oblong. It can be constructed as a flat bag and filled with batting (22) or other filling. Two rectangular single thickness flaps (16) are sewn to the sides of the middle section (10). To cover the baby, the lower part of the middle section is folded over the infant's body, and the two flaps are folded across it and tied together to hold it in place. A detachable square pad from a waterproof and/or stain resistant material can be placed on the middle section of the cover-up in a position optimal for protecting it from leaking diapers and for keeping it dry and sanitary.
