Here's the information I want every family to know. Children are falling from windows at an alarming rate – more than 3,300 kids five and under go to the emergency every year. Window falls are a completely preventable.  All windows should have window guards, child safe window stops or 4-inch window opening limiters.  We recommend Guardian Angel window guards, KidCo window stops or KidCo mesh window guards because these all meet ASTM safety standards.
