Despite the feeding-related difficulties last night, there was a bright spot as well. Ruby finally began showing visual interest in books!
Not only that, but she concentrated her unusually long attention span on a cardboard book (Sometimes I Like To Curl Up In A Ball) for maybe 15 minutes straight. She flipped the pages back and forth as well as she could, given her dexterity level. She looked with interest at the pictures, and was quietly intent the whole time.
