Thank you all again. Super support Tried the floor, it was a disaster. He didn't want to nap, just play. I'm going to start smaller, getting him to pull off my breast. That seems like a good starting point.
I was thinking I had failed him because a 16 month old should be able to sleep in his crib or spend time alone in his crib, but I realize now that is not success. Success is that I have been able to get him to nap everyday since he was born. Sleep that makes him happy and his brain grow. I am a good mom. As I lay with him in bed today I reminded myself that this won't last forever, and when it is over it will be sad. So for now I will take it slow and continue to enjoy it.
I'm excited to have found this forum as well...Best wishes, mamas!
