A number of people in that thread mentioned raising outlets to around 4' for child safety. How about the new "hanging hazard" created by having cords plugged in and running down to toddler level. A cheap lamp cord would probably pull right out of the receptacle but a heavier, three prong one may not. A heavier duty rubber cord could grip quite well if the young'un spun it around his/her neck. The hazard created by having uncut window blinds in a home with children is well known!

I think I just spun off on a tangent.
