May 01, 2025 By SwaddleAn

Getting your baby to sleep can feel like a mystery—but with a gentle, consistent routine, it becomes a rhythm. A safe and predictable sleep environment helps babies fall asleep faster, stay asleep longer, and feel more secure.The key? Start small, stay consistent, and adjust as your baby grows.In this guide, we’ll walk you through how to build a safe, age-appropriate sleep routine from the newborn stage through toddlerhood—and which SwaddleAn sleepwear pieces can help along the way.


Safe Sleep Basics (For Every Age)

Before we dive into routines by age, here are foundational safe sleep practices:

  • Always place baby on their back to sleep, in a crib or bassinet free of pillows, blankets, or toys
  • Maintain a comfortable room temperature (20–22°C / 68–72°F)
  • Dress baby in breathable layers and use a baby sleep sack instead of loose blankets
  • Choose well-fitted sleepwear (not too tight or too loose)
