A neonatal drape device for protecting a neonatal subject comprising a sheet configured to receive the neonatal subject in a supine position. The sheet has a base, at least one side edge, and a plurality of separation lines. The separation lines extend inwardly from the at least one side edge of the sheet. The sheet is sufficiently pliable so as to wrap and conform to the neonatal subject. The sheet further includes a plurality of notches disposed adjacent to the base, each at an inner end of one of the separation lines. The notches are configured to allow a cable to extend from an internal space of the neonatal drape device to an external location while the sheet is wrapped around the neonatal subject.
