Your baby’s sleep patterns have suddenly changed at the 4-month mark! You’re wondering when does 4 month sleep regression end.
Naps become shorter and nights feel longer, but not in a good way. One day your baby sleeps well, the next they’re waking up every hour. Parents feel confused about what happened.
This blog explains how long sleep disruption typically lasts and shares practical tips to help you find it.
What is the 4 Month Sleep Regression?
The 4-month sleep regression is a common stage when your baby’s sleep suddenly becomes lighter and more broken. It usually happens around 3.5 to 4 months of age. Before this stage, many babies sleep for longer stretches.
During this time, your baby’s brain is growing fast. They’re learning new skills, like rolling over or recognizing routines, and their sleep cycles are changing to include lighter sleep, just like adults.
These changes mean they may wake up between sleep cycles and need help going back to sleep.
Many parents also ask, when does 4 month sleep regression end, especially when nights feel long and restless.
Even though it’s called a “regression,” it’s actually a step forward in your baby’s development. It’s a sign they’re growing and learning. While it can be tiring, knowing what it is helps you support your baby through it and reminds you that it won’t last forever.
Signs of the 4-Month Sleep Regression
Recognizing the signs of the 4-month sleep regression can help you better handle this stage. Here are some common clues:
1. Frequent Night Wakings: Your baby may start waking up more often at night, even if they used to sleep for longer.
2. Shorter Naps: Naps may become shorter or more unpredictable.
3. Increased Fussiness: Babies can be fussier and harder to settle, both during the day and night.
4. More Difficulty Falling Asleep: Your baby may resist sleep and need more help to settle.
5. Startling or Jerky Movements: As their system matures, they may jerk or startle themselves awake.
6. Changes in Sleep Patterns: Their regular schedule might stop working, with early waking or bedtime struggles.
