The Wee Thumbie, for hospital use only, is the first pacifier designed specifically for use by very low birth weight babies. Modeled after the size and shape of the preemie thumb, this pacifier facilitates the important sucking behaviors normally learned in utero. Its uniquely-shaped nipple helps to keep the pacifier in the babyâ€™s mouth and its smaller-sized perioral guard keeps the pacifier centered and allows space for oral and nasal tubing. These pacifiers help calm and soothe distressed babies. Once the baby is breast or bottle feeding, he or she should transition to the Wee Soothie or Soothie pacifier. Wee Thumbie meets all Consumer Product Safety Commission requirements for pacifiers and provides an economical way to ensure that every low birth weight baby has the benefit of the Wee Thumbie to support its developmental needs. WARNING â€“ This Pacifier Is For A Premature Baby (gestation age 30 weeks of less). Use Of This Product Beyond The Recommended Age Could Pose a Choking Risk. Please Consult With Your Physician.
