Swaddling is the traditional practice of wrapping a baby up gently in a light and breathable blanket. This helps them feel calm and sleepy. There are two types of swaddles: traditional and two-in-ones. Traditional swaddle blankets are larger than receiving blankets and can have zippers, velcro, wings, and other features . Two-in-one or transitional swaddles allow you to wrap your baby snuggly or to have its arms up,down or out, depending on the product. By securely wrapping your baby in a swaddle, it will provide both comfort and security for the baby by making them feel like they're back in the womb.
