Got this and couldn't hold out till Valentine's Day, so I gave it to my girl a few days ago and she's crazy about him. She wanted him in bed with us while we watched Truck r' Treat again tonight 
Now she wants the 15". I hope I didn't create a monster!
Yea, I see it takes a little messing around and finding the sweet spot, but he can definitely stand decently

After messing with him for a bit he does indeed stand on his own, it was just a bit tricky and for the first few days he kept falling down. I'm happy to say that he stands up on his own perfectly now.
