I wonder if toddlers were part of the beta group to test smart phones. Jack certainly seems to navigate intuitively. His screen time is limited, but he grabbed Meg's phone when she was otherwise occupied, and I in turn grabbed this digital shot.
My grandsons are fascinated with my iPad (could be the games I put on it just for them!) but I too have to watch the amount of time they spend on it. It's really not good for their eyes- mine too! This is very cute!
