How do you keep the kids out of stuff? (without the use of duct tape)

I don't know how your house is set up, but when my son was that little I just put up a baby gate to keep him out of the kitchen and kept the bathroom doors closed. You could always keep anything dangerous stored in one of your bathrooms and let your two year old have free reign over your cabinets.

I stopped using the child safety latches because my kids could get into the cabinets anyway. The way I dealt with it was to take everything that could be harmful to them out of cabinets they could get into and put things in the cabinets that were either of no use to them or things that were harmless like tupperware containers, pots and pans. Eventually, they lost interest knowing they could go in them any time they wanted to. I think when they can't get into them, they just want to get into them more and when they realize they can, they get bored and move on to something else.
