Is It Sleep Regression or Something Else? How to Tell the Difference

When your baby starts waking at night or skipping naps, the first thought is often: sleep regression. But what if it’s something else?

Sleep disruptions can have multiple causes. Understanding what you’re dealing with will help you respond in the right way.

How to Spot a True Sleep Regression

Sleep regressions are:

• Sudden and often age-specific (4, 6, 8, 12 months, etc.)

• Not linked to illness or teething

• Often coincide with developmental changes

• Accompanied by short naps, night waking, and fussiness

Other Causes to Rule Out

• Teething: Gum pain can wake your baby and cause general irritability

• Illness: Colds, ear infections, and tummy bugs affect sleep

• Growth spurts: Hunger and crankiness are common

• Disruption: Travel, sleep environment changes, or stress at home

The Sleep Regression Checklist

Ask yourself:

• Has my baby just reached a developmental milestone?

• Are they showing no other symptoms of illness?

• Has their sleep suddenly changed with no clear reason?

If the answer is yes to most of the above, chances are it's a sleep regression.

When to Call the GP

If your baby has a fever, rash, persistent crying, or any symptoms that concern you, always seek medical advice. Don’t assume it’s “just a phase.”

Tips for Managing Any Sleep Disruption

• Keep a sleep log: Tracking patterns helps identify causes

• Maintain routines: Familiarity is reassuring

• Offer comfort: Whether it’s regression or illness, your baby needs you

• Don’t panic: Most disruptions resolve with time

Trust Your Instincts

You know your baby better than anyone. If something feels off, seek support. And if it is sleep regression? Then you’re already on the right path by learning more.

Sleep disruptions are hard, no matter the cause. But with the right approach, you can help your baby (and yourself) through the toughest nights.
