The "ehhhhen" phase

Ladies and gentlemen I present you "the ehhen"phase. It's very frustrating for mommy as most of the times he's whining about the forbidden objects and he doesn't want to give up on them. No matter how hard mommy or papa is trying to use the good ol' method of shifting his attention towards other activities not to mention the pile of toys, he's focused on the Other Thing.:)
I'm just very curious how much is just a stage in his development and how much is just pure personality.
More to come, I'm sure....
