If your baby cries intensely almost every day around the same time, without being hungry, wet, or ill, this might be the well-known pattern of colic. It affects roughly one in five babies, usually starting in the second or third week, peaking around the sixth month, and then gradually easing afterward, often with no clear reason why.

How Do You Know It Is Colic and Not Something Else?

Colic is medically described using the «rule of threes»: crying for more than 3 hours a day, more than 3 days a week, for more than 3 consecutive weeks, in an otherwise healthy, normally growing baby. It usually happens in the evening, often paired with the baby pulling their legs toward their belly, tensing their body, and a flushed face during intense crying.

What Actually Causes Colic?

The exact cause of colic is still not precisely known. Theories include temporary indigestion, sensitivity to a particular protein in milk, gas building up in an immature digestive system, or simply the baby's difficulty regulating emotions at this early stage. What matters is knowing that colic is not the result of something you did wrong in caring for your baby.

  • Hold your baby in the «football hold» or lying face-down along your forearm — this sometimes eases pressure on their belly.
  • Try gentle, rhythmic rocking, or a steady droning sound like a fan or a vacuum.
  • Swaddle them snugly but comfortably — the feeling of containment noticeably calms some babies.
  • Gently massage their belly in clockwise circular motions to help ease gas.
  • Do not hesitate to ask your partner or a family member for help so you can take a short break when you need one.

When Should You Ask a Doctor?

See a pediatrician if the crying is accompanied by fever, repeated vomiting, blood in the stool, repeated refusal to feed, or if the crying feels completely different from usual. This matters to rule out any other medical cause, and to reassure you that everything is normal — that reassurance itself has real value too.
