Bigplanz,
I can see how at Lowes a box of 10 Tr receptacles are not expensive. However what happens if you don't have these big box stores nearby? The local supply houses can mark up those TR receptacles a lot and then the cost to install might be an issue.
As for when a house becomes full of children, shouldn't the parents of those children take responsibility for the well being of their own children? I know I had tons of those little plastic plugs in the receptacles when my children were growing up.
