Obsessive behavior

Carly is obsessed with standing up. She wants to stand constantly...next to the couch, the table, holding my fingers, etc. It doesn't matter who or what as long as she's standing. In fact, if you try to distract her by sitting her next to her with her brother or sister, two minutes will pass and then she is whining to be stood up. She's completely and utterly obsessed with this new trick. So much so that the first thing she tried to do in the bathtub was stand up. All I can do is shake my head, watch closely, and be ready to jump in and save her when she goes tumbling. And pray that she doesn't take Keira with her. Thank God Keira isn't in the same mind set. Yet. Oy.
