The Cutie PAT Preemie Kit is designed for both preemies and newborns, offering a Preemie Tiny version, and a Preemie Stage 1. The Preemie Tiny is for babies up to 35 weeks, and the Preemie Stage 1 is for babies over 35 weeks. The Preemie Stage 1 is the same pacifier nipple as our Cutie PAT Round, and is safe for newborns up until 6 months. Once baby develops teeth, transition to a 0M+ or a Stage 2 Cutie PAT, for babies with or without teeth. The Preemie Tiny and Preemie Stage 1 are a safe, one-piece design made out of 100% medical-grade silicone. It has a notched shield that allows room for breathing, CPAP tubes, ET tubes, tube feeding, etc. The slim shield and the small beaded design both ensure that the Cutie Preemie is lightweight. Babies grow and change so quickly in those first few weeks. That's why the Preemie Pacifier Kit comes with two stages, so you'll always have what your baby needs next.
