When does the crying curve begin?

The crying curve typically begins in the first few weeks of a baby's life and can peak around six to eight weeks. This period is characterized by increased crying, which often reaches its highest intensity before gradually declining over the following months. The crying curve is associated with normal infant development and is often related to the baby's adjustment to life outside the womb. By the age of three to four months, most infants show a notable decrease in crying episodes.
