Get up, stand up

For the past few weeks all Jordan wants to do is fight for his right to stand up. He gets a possible standing area in his sights and aggressively crawls to it. There is no stopping him. His bedtime routine now consists of refusing to sleep by standing up in his crib. He'll hold on for a long time until he tires and his poor little legs/arms finally give out. Team safety thinks it's time to lower the crib.
