Newborn (0-4 weeks)

Understanding your newborn's sleep patterns

Why those first weeks feel so unpredictable

The Millie's Team By The Millie's Team · Parenting Notes

During the first few weeks, your baby's sleep may feel completely random. This is normal. Newborns haven't yet developed a circadian rhythm, so they sleep in short bursts throughout the day and night.

What is happening

Your baby's brain is still developing the internal clock that helps distinguish day from night. This process typically begins around 6-8 weeks and becomes more established by 3-4 months.

Around 6-8 weeks, you may start to notice slightly longer stretches of sleep at night. This is a sign that your baby's circadian rhythm is beginning to develop.
