We are just about to transition our 6mo to his cot. Our plan is to start with daytime naps and work up to the night time. There are plug sockets on the wall behind his cot, which we've covered with the socket covers. But there is also an old aerial plug which he could get his little fingers into. We've pulled the cot away from the wall for now but wondered whether there were any possible solutions? I know we can use bumpers but is it possible / safe to screw a large piece of plastic to the outside of the cot so he can't reach through?
