  • Method for using an infant garment with crossed over arm positioning sleeves
    Patent number: 5129406
    Abstract: An infant garment, particularly for premature and drug addicted infants, that is comprised of a saclike body with two extended sleeves that cross over each other, wrap around the child, and then attach in the back. The garment places the child's arms in the midline position and constrains them to prevent unnecessary motor releases. The garment is designed to allow for passage of test leads and tubes through the opening in the front of the garment while the garment remains closed. The garment swaddles the infant in warm clothing and will enable the child to rest more easily.
