This episode is part of the Not Just Theories Infant Sleep Series, exploring the many factors that influence baby sleep, from circadian rhythms and temperament to medical and sensory differences.

Infant sleep advice often focuses on bedtime routines and nap schedules, but in this episode, we zoom out and start somewhere else entirely.

In Episode 26 of Not Just Theories, I explore infant sleep through the lens of wake-up time, early morning light exposure, and sleep pressure, and why these factors matter far more than most parents are led to believe. We talk about how light helps regulate circadian rhythms, why a consistent morning start can support sleep across the whole day, and how this framework can feel very different from traditional schedule-based approaches.

I also begin to introduce ideas from the Possums Sleep Program, particularly the concept of shorter daytime naps and building enough sleep pressure for night time sleep (without rigid routines or ignoring a baby’s cues).

This episode is general education, not sleep training or medical advice. Every baby and family is different, and if you have concerns about your infant’s sleep, feeding, or development, please speak with your GP or child health professional.

This conversation is about understanding the why behind infant sleep... so you can make choices that fit your baby, your nervous system, and your family.
