We purchased a new 'toy' for Caroline - what we've dubbed the "Freedom Perimeter" (we're hoping she doesn't grasp the Orwellian doublespeak). Caroline is currently happily crawling around inside, as yet unaware that her exploration of all things dangerous in our living room has come to an end. Unfortunately, the "Freedom Perimeter" is made of plastic, so my idea of fortifying the barriers with an electric shock "Learning Current" will be difficult to implement.
