Any help?

We are having a time of it with Riley and bedtime. We have tried every method except for duct taping her to the bed (which we are considering). She gets up constantly, plays with everything, and pretty much does everything she's not suppose to. We've tried putting her to bed later so she's more tired, nope...we've tried sitting with her until she falls asleep (which is what Adam is doing right now)...that kind of works, but takes an hour of crying and correcting her to stay on her bed. I don't know what to do! I don't want to put her back in her crib...regressing just doesn't seem like the answer, but this is not working at all! Any ideas? I am open to anything...(and duct tape is still an option).
