About 2-3 months after the birth of my first child, I started “seeing” the baby’s face vividly whenever I would close my eyes, when I was falling asleep but other times during the day as well. It was not a conscious-voluntary imagination, more like an artifact of my brain rewiring priority numero uno. Our second child is now 3 months old and I have not experienced similar, perhaps because the brain changes already settled down before his birth.

Tetris effect, but with the baby!
