Developmental Milestones and the 8-Month Sleep Regression

At 31 weeks, your baby is approaching the 8-month mark, a time notorious for sleep disruptions. This period is often referred to as the 8-month sleep regression, but I prefer to call it a progression. Your baby's brain and body are working overtime, and this incredible growth can temporarily derail sleep.

Understanding Your 31 Week Old Baby's Sleep Needs At 31 weeks old, your baby's sleep needs are shifting. Most babies at this age require around 14 hours of total sleep within a 24-hour period. This is typically broken down into 11 to 12 hours of nighttime sleep and 2 to 3 hours of daytime sleep spread across two or three naps.

If your baby hasn't dropped that third late-afternoon catnap yet, they likely will soon. This transition can sometimes lead to overtiredness, which ironically makes it harder for babies to fall asleep and stay asleep. The key is to watch their wake windows closely and adjust bedtime as needed. Typical Wake Windows for a 31 Week Old Wake windows - the amount of time your baby can comfortably stay awake between sleep periods - are expanding. For a 31-week-old, wake windows generally range from 2.5 to 3.5 hours. A common pattern is a shorter wake window in the morning and a longer one right before bed.
