We went through this exact same thing at about the same age. It think with some kids it's just inevitable. I don't think it has anything to do with co-sleeping.
We also have a crib in our room where ds takes his naps. What we would do is if he woke up and was really bright-eyed and bushy tailed, we'd put him in his crib with a couple of toys and let him quietly play for a while while we dozed. Occasionally, he'd lie down on his own and fall asleep, but more often than not after 20-30 minutes of quiet play, he'd stand up and 'call for us' and we'd take him back into bed and get him settled back down again rather easily. That's what worked for us.
I bet your dd will eventually outgrow this, as our ds did, but until then maybe you could try what we did.
Ooh, I just reread your post and you say she's waking up every hour! Oh boy! Ds usually just did that once or twice a night. Is your daughter teething? Or sick? I'm not sure what would make a baby who usually sleeps well get up every hour.
There have been occasions, not many, where ds had a hard time settling back down after one of his 3am play sessions. When this has happened, I just keep laying him back down when he tries to crawl away. He usually protests for a while and even cries a little bit. Sometimes we as parents have to set limits.
