Babies exist so us grown babies can struggle to figure out what’s wrong with them

When my son was an infant he would cry and grab my hand (hard!) and pull it toward his body. I would rub him but it wouldn’t do any good but if I tried to pull my hand away he would grab it again. Turns out he wanted to be lightly scratched. As soon as I figured that out he would right asleep. Too bad it took three months.
