A friend of mine is helping to make the Cogni Case and I thought it was a great idea worth sharing. I don't have a child, but I recognize the problem space and challenge new parents have creating memories of their newborns. This is potentially a really effective, and dead-simple solution!
From the creators: "Cogni Case uses interchangeable art cards with STIM inspired designs to engage your child's gaze to the back of the phone, allowing you to take clear and well positioned photos of them anytime. The placement of the graphics on the art cards creates a temporary engagement between the infant and the camera, resulting in better photos, videos and video calls."
