My son has chunky thighs so always has to size up in footie pajamas, which then of course makes them too long for him. The footies kept coming off of his feet and he would trip over them or get tangled up... then I discovered this neat little trick!

Spiral/ coil Pony holders around the ankles! They keep the feet on but don't get too tight to cut off circulation! Lifesaver!!

Ps. If you aren't using these in your hair yet you will want to get them a try, they are amazing!
