Crate
I leave Bogey (he's 1yr old tomorrow) in the crate while I'm at work as well. I feel the same way most of you do. Sometimes when I leave I just feel terrible, but I've come to realize that it is best (safest) for them.
I left him in the front room once four about 4 hours, which has a bed and two dressers and that's it, no wires or blinds he can get to. I came home to the biggest mess I'd ever seen. All the sheets, bedspread and pillows had been torn off the bed he marked the bed twice and left me a nice little present in the corner. I was mad but I couldn't help but laugh, after I told him he was bad and put him outside. After that I knew he be crated for a while.
Even though you think they are the smartest little angel in the world, given the chance or after getting bored there's no telling what they can get in to. Usually when I'm in the shower I let him run around down stairs. He normally goes in the front room and lays on the bed to look out the window. Well, when I got out of the shower he wasn't in the front room so I went upstairs in the computer room. I *had* a really nice pair or computer headphones which he had previously shown no interest in. He must have gotten bored and decided to chew on them. Now all the doors are closed to every room except the front room.
I leave him is food, if he hasn't already eaten it before I go to work, toys, a kong with penut butter and a few liver treats stuffed in the bottom of the kong, and a bowl of water, which, thank goodness he hasn't turned over yet.
Your baby will eventually get used to it.
Once small piece of advise is to never use the crate as punishment. You want her to think of the crate a a "den" and not a place she's put when she's been bad.
Hang in there it'll get better
