Why Baby Sleep Isn’t Linear - And That’s OK


One of the biggest myths about baby sleep is that it should improve in a straight line. In reality, it’s far more up and down. Understanding this can help you approach sleep regression-and parenting in general-with more patience and confidence.

The Truth About Baby Sleep Patterns

Babies don’t gradually sleep more every month. Instead, they go through periods of progress followed by setbacks:

  • Longer stretches of sleep… then constant waking

  • Predictable naps… then refusal to nap entirely

  • Calm evenings… then crying at every bedtime

This can be deeply frustrating, especially if you’ve worked hard on sleep routines. But it’s normal.

Why Sleep Isn’t Linear

  1. Developmental leaps: Just when sleep improves, your baby starts crawling or teething.

  2. Growth spurts: Babies need more food and comfort, disrupting sleep.

  3. Environmental changes: Holidays, illnesses, and milestones all affect rest.

Sleep will improve again. But there will be bumps—and that’s part of the journey.

Shifting Your Mindset

Rather than expecting constant improvement, look for:

  • Trends, not perfection

  • Adaptability, not rigid routines

  • Connection, not control

Give yourself credit for the good nights. And give yourself grace for the hard ones.

What Progress Really Looks Like

It’s better to think of baby sleep as a spiral not a straight line. Each regression may look like a step backwards, but it’s usually a sign of your baby developing in incredible ways.

With each challenge, your baby gains new skills-and you gain confidence in your ability to support them.

Final Thoughts

There’s no such thing as a perfect sleeper. But every disrupted night brings you closer to understanding your baby and strengthening your bond.

The road isn’t straight-but you’re still moving forward.
