Co-sleeping

During my entire pregnancy I could've written a book on how strongly against co-sleeping I was. Now, with my (almost) 4 week old baby girl, she is making me believe that co-sleeping is the only way she will fall asleep. It gives me such anxiety because I am aware of the risks but also feel like as I'm sleeping I am aware not to roll over her or smother her.. Am I crazy? Our sleeping positions are her laying chest to chest on me or her in my arm crevasse. I wake up very frequently to check on her. I still don't like the idea of co-sleeping but it's the only way she will sleep. Seriously.
