Why Muslin?

Muslin is a unique cotton fabric first introduced into England in the late 17th century. Muslin has a light, open weave that allows air to flow seamlessly through the material. The soft natural fibers allow your baby's body temperature to adjust naturally, eliminating over-heating, but ensuring warmth and comfort. These wraps will allow you to safely swaddle your baby, giving you confidence that your baby will experience a peaceful and secure sleep.
