hang in there, sweetheart, this too shall pass.
Our daughter did this to us. She would climb out of her crib, go downstairs without ever waking us and plunder the house. I had to have my glasses replaced twice. Here is what we did.
We put a "dutch door" on her bedroom, closed off all of the electrical outlets with protectors that she couldnt get off and put a lock that she couldnt reach on the outside of the dutch door. (a dutch door is like a barn door, both halves open but you can open the top and close the bottom)
we left her her toys and took the side off of her crib so she wouldnt fall getting out of it. She could get up and roam her room all she wanted but we made it clear that once she was "in bed" that we were not going to let her out again until morning, whether she was awake or not. We would go to the door, tell her hello, and tell her to go back to bed. Then we would go back to bed ourselves. It took about 2-3 nights before she realized that she was not going to get our attention this way and she would play until she got sleepy and go and get in her bed. And she was only about 2 years old at this time.
I hope this helps. The door helped us remove ourselves from her environment and taught her that bedtime was bedtime.
You are in my prayers.
