We have to impose some kind of discipline for bubby. He is getting a little wild and screams when told no. He does the scary things too like climbing to get to the light switch or dragging his toy box to step on to get to the phone, or banging on the window. We are afraid he is going to fall and hurt himself. Or worse the glass would break and hurt him bad. I know he is just a kid and he wants to learn about the things around him but still what he's doing isn't safe for him. And for our sanity. Any ideas?
