Baby sleep in the 4th month: what changes are noticeable now

Babies at 4 months of age need an average of between 12 and 16 hours of sleep within 24 hours. This includes both the longer sleep phases at night and two to four naps during the day. It is important to note: Every baby has its own sleep requirements – slight deviations are completely harmless.

Yes, around the fourth month, many babies experience what is known as a sleep regression. This phase can cause previously better sleep to suddenly become more restless again. This is part of natural development and usually regulates itself over time – patience and a constant routine are particularly helpful now.

Typical signs of tiredness at this age include yawning, rubbing eyes, a blank stare, or fussiness. Some babies also become restless or seek increased closeness. Pay attention to these cues – putting your baby to sleep in a timely manner can prevent overtiredness and make falling asleep easier.

Gentle routines, dimmed lights, or soothing sounds support falling asleep. Bouncy sleep aids such as a swing2sleep automatic baby hammock with motor can also help to let the baby gently settle down – especially in phases of increased restlessness or after a very active day.

Compared to newborn sleep a clearer pattern emerges in the fourth month: longer nighttime sleep phases, more distinct waking times during the day, and often a stronger orientation towards external stimuli such as light and noise. The nervous system is also more developed now – which, however, makes sleep more sensitive to disturbances.
