Babies who don’t cry or fuss are often called “good” babies. “Good” babies sleep through the night and don’t bother their caregivers. I feel sad when I hear parents speak this way. Sleep patterns have nothing to do with being a “good” or “bad” baby. Infant cries aren’t signs of poor character. Biology fuels crying to bring a caregiver close—babies cry because this is how they communicate. Communication is central to bonding. And bonding is core to survival.
