Sleep - the never ending battle

My little one is just about 8 months and I am at a loss for what to do about her sleep. She was pretty good for awhile, was weaned from night feedings, and we did a little sleep training around 4 months. Recently she is up 3-5 times a night. If I leave her in the crib she crawls and bonks her head, stands and grabs the camera and any other ruckus she can think of. I don’t know how to sleep train her safely. Any ideas? Anyone in a similar situation? Also has anyone purchased takingcarababies?
