    A SMARTER SWADDLE​​​​

    Not only does swaddling mimic the snug embrace that sleeping babies love in the womb, it also prevents wild hand movements that can startle little ones awake. Proper swaddling is one of the most beloved and ancient parent practices. It keeps babies soothed and happier all night long.​​​​‌‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‍‌‍‍‌‌‍​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍‌‍‍​‌‌​‌‌​‌​​‌​​‍‍​‍​‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‌‌‍‌​‌‍‌‌‌‌‍​‍‍‌‍‍​‌‍​‌‌​​‌​​‌‍‍‌‌‍‌‌‌​‌‌​‌‍​‍‌‍​‌‌‍​‍‌‍‌​‍‍‌‍​‌‍‌‍‌​‍‌‍‍‌‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‍‌‍‌‌‍‌‍‌​‌‍‌‌​‌‌​​‌​‍‌‍‌‌‌​‌‍‌‌‌‍‍‌‌​‌‍​‌‌‌​‌‍‍‌‌‍‌‍‍​‍‌‍‍‌‌‍‌​​‌‌​‌‍​‍‌‌​‍​‌‌‌‌‍‌‍‌‍‍‌‌‍‍​‌​​‌‍‍‌‍‍‌​‌‍‌‍‍‌​‌‌‌​‍‌‍‍‌‍‍‍‌‌​​‌‌​‌‌‌​‌​​‌‌​‌‌​‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌​‍‌‍‌‍‌​‌‌‌‌‍​‌‌​​‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌​‌‍‌‌‌‍​‌‌​‌‍‍‌‌‍‌‍‍‌​‌​​‍‌‍‌‍‌​‌‍‌​‍‌‌​‌‌‌​​‍‌‌‌‍‍‌‍‌‌‌‍‌​‍‌‌​​‌​‌​​‍‌‌​​‌​‌​​‍‌‌​​‍​​‍​​‍‌‍‌​​‌‌‌‍‌‌​‍‌‌‍​‍‌‍​‍‌‍​‌​‌‌‌‍‌‌‌‍‌‌‌‍​​‍‌‌​​‍​​‍​‍‌‌​‌‌‌​‌​​‍‍‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍‌‌​‌‌‌​​‍‌‌‌‍‍‌‍‌‌‌‍‌​‍‌‌​​‌​‌​​‍‌‌​​‌​‌​​‍‌‌​​‍​​‍‌‍‌‌‌‍‍​‍‌‌​​‍​​‍​‍‌‌​‌‌‌​‌​​‍‍‌‌‍‌‍​‌‌‍​‌‌‌‌‍‌‌​‌‍​‍‌‍​‌‌​‌‍‌‌‌‌‌‌‌​‍‌‍​​‌‌‍‍​‌‌​‌‌​‌​​‌​​‍‌‌​​‌​​‌​‍‌‌​​‍‌​‌‍​‍‌‌​​‍‌​‌‍‌​‌‍​‌‌‍‍‌‍‍‌‌‌​‌‍‌​‍‌‌‍‌​‌‍‌‌‌‌‍​‍‍‌‍‍​‌‍​‌‌​​‌​​‌‍‍‌‌‍‌‌‌​‌‌​‌‍​‍‌‍​‌‌‍​‍‌‍‌​‍‍‌‍​‌‍‌‍‌​‍‌‍‌‍‍‌‌‍‌​​‌‌​‌‍​‍‌‌​‍​‌‌‌‌‍‌‍‌‍‍‌‌‍‍​‌​​‌‍‍‌‍‍‌​‌‍‌‍‍‌​‌‌‌​‍‌‍‍‌‍‍‍‌‌​​‌‌​‌‌‌​‌​​‌‌​‌‌​‍‌‍‌‌​‌‍‌‌​​‌‍‌‌​‌‌​​‌​‍‌‍‌‍‌​‌‌‌‌‍​‌‌​​‍‌‍‌​​‌‍​‌‌‌​‌‍‍​​‌‌​‌‍‌‌‌‍​‌‌​‌‍‍‌‌‍‌‍‍‌​‌​​‍‌‍‌‍‌​‌‍‌​‍‌‌​‌‌‌​​‍‌‌‌‍‍‌‍‌‌‌‍‌​‍‌‌​​‌​‌​​‍‌‌​​‌​‌​​‍‌‌​​‍​​‍​​‍‌‍‌​​‌‌‌‍‌‌​‍‌‌‍​‍‌‍​‍‌‍​‌​‌‌‌‍‌‌‌‍‌‌‌‍​​‍‌‌​​‍​​‍​‍‌‌​‌‌‌​‌​​‍‍‌‍‌​‌‍‌‌‌​‌‍​‌​‍‌‍‍‌‌​​‌‌​‌‍‍‌‌‍‌‍‍​‍‌‌​‌‌‌​​‍‌‌‌‍‍‌‍‌‌‌‍‌​‍‌‌​​‌​‌​​‍‌‌​​‌​‌​​‍‌‌​​‍​​‍‌‍‌‌‌‍‍​‍‌‌​​‍​​‍​‍‌‌​‌‌‌​‌​​‍‍‌‌‍‌‍​‌‌‍​‌‌‌‌‍‌‌​‍​‍‌‌
