How many puzzles can she do?

Tonight Faith had too much energy for bed. Instead of settling down to read she decided she was going to do her puzzles. Tonight after completing one, she would set it aside and call that her completed pile. I thought she may get four or five in the pile however she continued to do her puzzles until every last one was finished and placed in it's correct pile. I heard her mumbling through her thoughts of where pieces go. She would say, "No, that's not right. Let's try it here. That just doesn't quite fit. Maybe it goes here." She did wonderful and was so proud to have her picture taken with her completed pile. After the count was in, there were a total of 11 puzzles that she did by herself. I helped her with some corner pieces but all in all she did them by herself. She sure loves doing puzzles.
