Kyte baby makes my ride or die sleep sack favorite for Cassidy 💛 We have been using a 2.5 TOG (pictured but it’s an old design) for winter, but she can also manage with a 1.0 TOG and that ones best for all year. She’s currently in a Size S & 5 months. Size M is for 6-18 months, and Size L for early toddler. kytebaby babysale babygear sleepsack favoritebabygear LTKfamily LTKsalealert LTKbaby
