First we have the stool in the sink. The stool is used so the boys can reach the sink to wash their hands, but Tim likes to just play in the water and play with the tooth brushes, and tooth paste. Making a huge mess. So the less he can reach the less mess we have (at least with the tooth paste)
Next we have the lock at the top of the door to lock the kids out... uh, I mean to lock the door so the kids can't get out.
I don't need a fancy door stop or anything. I just throw a blanket over the top of the door to keep any fingers from getting smashed.
So Tim really likes to play with water. So the easy way to fix that is to take the handle off. Tim is quite clever... I opened the plug one night after his bath. Well Tim didn't want to get out so he closed the plug and turned the water back on. Then the next morning I woke up to Tim turning the bath water on and off. Quick fix... take the handle off.
Baby gates can get expensive so next best option.... Just screw a board into the wall.
After our old TV broke we got a new one. One day we were all playing and a toy was thrown and hit the TV, the next day Steve came home with a large piece of plexi glass to put in front of it. I have to say... people laughed... oh, they did. Yeah until our neighbor saved up... bought a new TV and three days later their son walked by with a broom and hit there TV, yeah they weren't laughing at our plexi glass after that.
There you go, there is my "real world" toddler proofing.
