No idea why baby is crying.
My husband and I made a lot of jokes about abandoning our baby for the wolves when she was a couple months old, because we just couldn’t figure out WHAT WAS WRONG to make the crying stop. We fed her, changed her, took her sweater off, put her sweater on, burped her, patted her, bounced her, you name it…sometimes, babies just cry. It doesn’t make you a failure as a parent. Sometimes they are itchy but don’t understand the concept of “itchy”, sometimes they just saw a cow for the first time and they still need to process it, sometimes they have a tiny invisible hair wrapped around a finger or toe and it hurts, or they need to fart and can’t or maybe they’re just in a bad mood, because god knows, even adults wish they could throw a fit occasionally. It’s okay for a baby to fuss, too, even if it does grate on your nerves.
