The lighting is strange in Claire's room in the morning, so the strange glow is from the iPhone flash. Below is another photo from the same "photo shoot" as it's getting harder to have Claire stay in one place. She wants to move!
She's always on the run, unless strapped into a seat of some kind. The purpose of the crawling is usually to get to higher ground, i.e. climb to a stand. She is not a fan of diaper or clothing changes - again because those activities take away from exploring.
