Potty Training??

I bought Sam a potty chair from a garage sale last summer and put it away because he was obviously too young. He saw one of his older friends using it one day and has been sitting on it once in a while for no reason at all. He won't let me take his diaper off - he just sits on it like it's one of his chairs. Now, he has started using it as a table. He actually carries it around and I caught him putting his bowl of snacks in it. Now, rest assured, it has been cleaned thoroughly so I wasn't too concerned about germs. I do think this is an indication that he just isn't ready for potty training just yet :)
