I can sympathize to a small degree with helicpotering in that it is scary to let your kid fail at something. It is scary to see them get hurt. BUT it is amazing to see that kid bounce back, dust the dirt from their knees, and try again. Raising K isn't about being in MY comfort zone. (she broke that at 2 when she insisted on climbing the Big Kid jungle gym at the park)
It is sad that this generation of over-parented kids is going to suffer so badly.
