What is a BabyOK Babe-Sleeper and how does it work?

It is a 100 percent cotton sleep-bag designed to fit 6–30-month-old infants, which allows the baby to comfortably roll from back-to-side and side-to tummy and allows the infant to sit up after finishing sleeping which making it challenging to push its blankets off, to protect it from the cold. It is portable, and it fits all cot sizes and designed for all year-round use.
