Infant Colic or Reflux-Like Symptoms? Signs, Causes, and Support

Understanding Colic vs. Reflux-Like Digestive Discomfort in Babies

A Supportive Guide for New Zealand Parents

Parenthood brings many moments of wonder — and a few challenges, especially when your baby cries and you are not sure why. In the early months, two common concerns are colic and reflux-like digestive discomfort. While they can appear similar, they have different characteristics and may benefit from different soothing approaches.

This blog gently explains the differences, possible causes, and simple ways many New Zealand families support their babies during this stage.

What Is Colic?

Colic describes long periods of crying in an otherwise healthy and well-fed baby. It often begins around 2 to 6 weeks of age, peaks by 6 weeks, and usually eases by 3 to 4 months.

Typical signs of colic include:

Crying for more than 3 hours a day, at least 3 days a week
Fussiness that is difficult to soothe
Crying that often occurs in the late afternoon or evening
Clenched fists, arched back, or knees pulled to the tummy

What Is Reflux-Like Digestive Discomfort?

Some babies experience frequent spit-up or unsettled behaviour after feeding. These signs are commonly referred to as reflux-like symptoms and are often linked to a still-developing digestive system.

Signs may include:

Bringing up small amounts of milk after feeds
Fussing or wriggling during or after feeding
Seeming more comfortable when held upright
Mild feeding discomfort not related to illness

Colic vs. Reflux-Like Symptoms: How They Differ

Feature	Colic	Reflux-Like Discomfort
Timing	Common in late afternoon/evening	Often after feeds
Cry pattern	Intense, prolonged crying	Fussiness linked to feeding or lying down
Spit-up	Not common	Frequently observed
Comforted by	Soothing techniques	Upright positioning, gentle burping

Possible Contributing Factors

Colic

Adjusting to life outside the womb
An immature digestive or nervous system
Sensory overload from light, sound, or routine changes

Reflux-like Digestive Discomfort

A developing lower oesophageal valve (common in babies)
Feeding too quickly or lying flat after feeding
Larger or less frequent feeds

Gentle Ways to Support Your Baby

To comfort colicky babies:

Try skin-to-skin contact or wearing your baby
Use white noise or soft, rhythmic sounds
Create a calm, dimly lit environment in the evenings
Offer slow rocking or cuddles during crying spells

To support feeding comfort:

Feed in an upright position and hold baby upright after feeding
Burp gently during and after feeds
Offer smaller, more frequent feeds when possible
Some families explore traditional, natural options used to support digestive comfort and occasional fussiness

When to Seek Advice

If your baby is consistently unsettled, not feeding well, not gaining weight, or showing signs that concern you, contact your GP, Plunket nurse, or midwife. They can provide guidance and rule out any underlying issues.

Conclusion

While colic and reflux-like digestive discomfort can feel overwhelming in the moment, both are often part of normal infant development. Understanding the signs and gentle ways to respond can make a meaningful difference.

You are doing a great job. If you ever need reassurance, do not hesitate to ask for help. Support is always close by.
