Ive got a monkey on my hands

So...at the sitter today she told me that V got out of her pack n play at nap time while they were all downstairs watching a movie. She said she found her up there sitting and reading books she had pulled off the shelf. I thought it was funny, but scary. So tonight, I tuck her into bed and she is asleep so I think and Im sitting in the next room doing homework. Next thing I know her bedroom door opens and out runs ms Vaughnie looking so proud. Scared me to death. She had climbed out of her crib, all by herself and she thought she was big stuff. I put her back in there and said show mommy what you did. and sure enough, she through one leg over and climbed down. WHAT? So I had to lay in there until i thought she was out and as soon as I opened the door to leave she snuck up and tried climbing out. I watched for about ten minutes and she tried to climb out about 20 times. She would wait til she thought i wasnt watching and then "wake up" and start to climb out. SCARY. Some times she had it under control,others she was about to fall on her head. What am I going to do? I really think those crib tents are horrible and like cages and very invasive and claustraphobic but im not sure that she is ready for a big girl bed yet....she'll just climb out of that too. Any suggestions? Plus we will be moving wednesday and we'll be upstairs. I am going to get baby gates for the stairs but if she can scale a crib she can surely climb a baby gate. The worry has begun. Yup, the easy days are done!
