Ok, We are going to try that. We woke up at 9:30 today and DD was still asleep, but I chose to pick her up and wake her. She actually woke up without crying this time.

That is funny, "how do you know they are up?" DD didn't cry one time while napping on the bed and I walked in to find her at the edge looking upset because she couldn't get down / was afraid (But I taught her her how to back off the bed after she crawled off one time at 7.5 months.) I have never used a monitor because she lets me know usually when she is up.
