Phototherapy infant swaddling blanket

1. A method of swaddling an infant undergoing a course of phototherapy comprising:

providing a sheet of fabric material of generally T-shaped configuration having a base region extending perpendicularly from a central portion of a cross region, the sheet of fabric material being >45% light-transmissive for light having a wavelength in the range of 350 nm to 500 nm; and

folding the sheet of fabric material about the infant so that the infant is snugly wrapped in the sheet of fabric material, the sheet of fabric material limiting arm and leg movement of the infant, with only a single layer of the sheet of fabric material being located between a phototherapy lamp and the infant when the phototherapy lamp is placed above the infant.

2. The method of claim 1 , wherein the fabric material is >90% light-transmissive for light having a wavelength in the range of 350 nm to 500 nm.

3. The method of claim 1 , wherein the cross region includes a first distal end and a second distal end, one on either side of the central portion of the cross region, and the method further comprises:

positioning the infant on top of the second distal end of the cross region;

wrapping the first distal end of the cross region around the infant in the direction of the second distal end until the first distal end is underneath the infant and the central portion of the cross region lies atop the infant's torso; and

wrapping a distal end of the base region underneath the infant in the direction of the head until the distal end of the base region is underneath the infant.

4. The method of claim 1 , wherein the cross region includes a first distal end and a second distal end, one on either side of the central portion of the cross region, and the method further comprises:

positioning the infant on top of the base region of the swaddling blanket with the infant's head at the distal end of the base region and the infant's feet at the proximal end of the base region;

folding the cross region up over the infant such that the central portion of the cross region lies atop the torso of the infant;

wrapping either the first or the second distal end of the cross region around the infant until such distal end is underneath the infant; and

wrapping the other of the first or second distal ends of the cross region around the infant until such distal end is underneath the infant.

5. The method of claim 1 , wherein the cross region includes a first distal end and a second distal end, one on either side of the central portion of the cross region, and the method further comprises:

positioning the sheet of fabric material over the infant so that the central portion of the cross region lies atop the torso of the infant with the infant's feet proximate the base region;

wrapping either the first or the second distal end of the cross region around the infant until such distal end is underneath the infant;

wrapping the other of the first or second distal ends of the cross region around the infant until such distal end is underneath the infant; and

wrapping a distal end of the base region underneath the infant in the direction of the head until the distal end of the base region is underneath the infant.

6. The method of claim 1 , further comprising directing light having wavelengths in the range of 350 nm to 500 nm through only the single layer of the sheet of fabric material into contact with the infant.

7. The method of claim 1 , further comprising utilizing one or more tabs of hook and loop material to affix one portion of the sheet of fabric material to another portion of the sheet of fabric material when the infant is snugly wrapped in the sheet of fabric material.
