Why do babies cry so much?

Answer: It's their main way to communicate needs before they can talk

They have more pain — Pain is one reason a baby cries, and research suggests babies feel pain at least as keenly as adults, but it accounts for only a small share of crying. Hunger, tiredness, a wet nappy, cold, overstimulation and simply wanting to be held all come out as the same cry, because crying is the one signal a baby has for everything.

Their brains are underdeveloped — Their brains are still developing, which is why they cannot yet use words or gestures, but immaturity itself is not what makes them cry. Crying is the signal they use because nothing else works yet.

It's their main way to communicate needs before they can talk ✓ — Correct! Babies can't talk, walk, or point to tell you what they need. Crying is their primary way to communicate hunger, discomfort, tiredness, or needing affection. It's an evolutionary survival mechanism that ensures caregivers respond quickly to their needs. As babies develop language and motor skills, crying decreases significantly.
