E. R,
I believe all these "bad behaviors" are simply a new stage of learning and exploring for Anthony. Keep in mind how facinating a refrigerator can be! Perhaps you can satisfy his curiosity by picking him up and pointing out the wonderful things in there, "OOoh, now Mommy's getting out the milk! Do you see the salsa anywhere? How many APPLES can we count... 1, 2, 3..." Not only will you be satisfying his curiosity, but you will also be developing his vocabulary. When ever he acts up, think about WHY he's doing it, or what he's frustrated about, and use it as a developmental opportunity. I also highly recommend the book, "What to Expect the Toddler Years". I have read mine ragged, but it has saved my sanity!
Something else to consider: For the truly dangerous places (in our case older brother's room with chokable toys), consider putting up a baby gate. He'll learn it's off-limits, and should eventually give up persuing it.
