User: Why do babies cry?
Assistant: Babies can cry from a variety of reasons. Either the baby is hungry, uncomfortable, needs a change of diaper or just in need of a hug. Babies cannot speak so the only way they express their emotions is via crying or smiling. When a baby cries they are typically looking for  attention or for you to address a matter for them. Try to see what is making your baby uncomfortable and try to address the root cause. When a baby cries uncontrollably and you cannot decipher the cause, check with your pediatrician.
