Potty Training Time?

So, I was feeding Belle dinner yesterday in the kitchen, only to look over and find Cooper taking off his diaper in the living room. Isabel was almost done with her food, so I decided to finish feeding her and then put Cooper's diaper back on. Less than a minute later, I look back at Cooper and see him peeing on the carpet! Hmmmm...I would love to think of this little episode as a sign that he's ready for potty training, but alas, still no interest!
