At what age do many parents report that infants typically start sleeping through the night?

Many parents often report that infants typically start sleeping through the night around 4 months of age. This period coincides with developmental changes in infants, where they begin to consolidate their sleep patterns. By this age, many babies have established a more predictable sleep-wake cycle, which can also be influenced by factors such as feeding routines and the maturation of the nervous system.

While some infants may sleep longer stretches earlier, commonly from around 6-8 hours at night, it is at approximately 4 months that a larger number of parents notice a significant improvement in their baby's sleep duration, leading to the perception that their child is sleeping through the night. This understanding is anchored in both developmental milestones and the experiences shared by a significant population of parents.
