When you place your baby on their back to sleep, their natural position is with their arms up. The Love to Dream Swaddle UP Original features a patented design that allows you to swaddle your baby with their arms raised in this more natural position. The medical reason behind baby’s desire to have access to their hands is that when they wake up at night, they want to self-soothe — simply by rubbing their cheeks or sucking on their hands. If they are swaddled with their arms restrained, they cannot do this, which causes them to wake up, get frustrated, and try to break free from traditional swaddles. Features: - 1 TOG - The Swaddle UP is a stretchy blend of cotton and elastane designed to be snug and comfortable around the torso, hold baby’s arms, and calm the startle reflex, encouraging a long and restful night’s sleep for both baby and mom - The Swaddle UP is safer than swaddling your baby with traditional blankets - With the Swaddle UP, no complicated wrapping techniques are required and there is no risk of dangerous loose blankets in your baby’s crib - The dual zipper design of the Swaddle UP allows you to change diapers while keeping baby swaddled, and it has no bothersome snaps, noisy Velcro, or tricky wrapping, ensuring your baby stays comfortably swaddled all night long - In addition, the Swaddle UP has plenty of room for baby to move their legs and hips, and has recently been recognized by the International Hip Dysplasia Institute (IHDI) as a “Hip Healthy” product.
