The aden + anais snug fit sleeved sleeping bag is designed to help babies (and parents) enjoy uninterrupted sleep. Its quilted, cotton knit fits snugly on the upper body and arms. The unique sleeve design makes little arms feel secure, helping to reduce the startle reflex from waking baby. This comforting cosiness mimics the secure feeling of the womb, encouraging a sounder sleep. Available in sizes newborn through to nine months, the sleeping bag’s leg room allows for continued healthy hip development, while a clever zip opens from the bottom up for no-fuss night-time changes.
