The sleepy bunny

I love the way Oscar flip flop herself to one side to sleep. She's been doing it ever since she was a baby bunny. The only difference is now she flip flop with a THUMP to bring down her dewlap and white tummy.  These pictures were taken at 2 different times.  Can anyone tell which pics are older and which are more recent? (Hint: You can tell by looking at the condition of the carpet.)
