All babies cry — it’s their main way of communicating. Crying usually increases from about 2 weeks, peaks around 6–8 weeks, and eases by 3–4 months. Colic is the name for long bouts of intense, hard-to-soothe crying in an otherwise healthy, growing baby — often described as more than 3 hours a day, more than 3 days a week. It’s exhausting, but it isn’t caused by anything you did, and it passes.

Key takeaways

  • Increased crying in the first months is a normal developmental phase.
  • Check the basics first: hunger, diaper, temperature, tiredness, wind.
  • Rhythm and closeness — swaddling, shushing, swaying, sucking — calm many babies.
  • If you feel overwhelmed, it’s okay to put your baby down safely and take a break.
  • Never shake a baby. Make sure every carer knows this.

The PURPLE crying period

Researchers describe this normal phase with the acronym PURPLE: crying Peaks around 2 months, is Unexpected, Resists soothing, your baby may look like they’re in Pain when they’re not, it’s Long-lasting, and often happens in the Evening. Knowing it’s a phase helps many parents cope.

Try one technique at a time for a few minutes before switching; too many changes can overstimulate.

  • Swallowed air: burp often and try paced bottle feeding — see our spit-up and burping guide.
  • Cow’s milk protein allergy can cause crying with blood or mucus in stool, eczema or poor weight gain — talk to your pediatrician before changing formula or your diet.
  • Overfeeding or fast flow can cause discomfort; slower nipples help.

Looking after yourself

  • Take turns with a partner, friend or relative — even 20 minutes out of earshot helps.
  • If you’re alone and reaching your limit, place your baby on their back in the crib, close the door, and breathe. Check back in 10–15 minutes.
  • Earplugs or headphones can soften the sound while you soothe.
  • Persistent low mood or anxiety deserves support — see our new parent guide for helplines.
Call your pediatrician if your baby’s crying comes with

  • a high-pitched or weak cry, unusual floppiness or sleepiness;
  • crying that starts suddenly after a fall or injury.
