I just read a post on another site where the person questioned whether to put up a "tot-finder" decal in their kid's bedroom windows. These decals save lives. The firefighters will know where to go to rescue your kids. This person was concerned about it advertising the kids location to an abductor.
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
