1. Understanding Infant Sleep Patterns
Babies have sleep patterns distinct from those of adults. They sleep longer overall but in shorter bursts, especially newborns. A key difference lies in the higher proportion of Rapid Eye Movement (REM) sleep, also known as light sleep (Barry, 2021).
1.1. REM Sleep Explained
During REM sleep, babies dream, their eyes move beneath their eyelids, and they may twitch or jerk. Their breathing can become irregular. These movements are normal and part of the sleep cycle (Leigh, 2016).
1.2. Brain Development During Sleep
During light sleep, the brain processes new memories and matches them with experiences (Barry, 2021). This intense mental activity can sometimes overwhelm babies, leading to crying.
2. The Six Stages of Infant Alertness
Babies cycle through six stages of alertness each day: deep sleep, drowsy, calm alert, fussy alert, and crying (Leigh, 2016).
2.1. Transition Between Sleep Stages
Crying out in sleep can indicate a transition between these stages. Often, babies will resettle themselves, but sometimes the change causes them to wake up fully.
2.2. Recognizing Alertness Stages
Understanding these stages helps parents respond appropriately to their baby’s needs. Knowing when a baby is drowsy versus fussy can guide sleep routines and comfort strategies.
3. Common Reasons for Crying During Sleep
Several factors can cause a baby to cry in their sleep. These include developmental leaps, discomfort, and environmental factors.
3.1. Developmental Leaps and Mental Progress
Mental development can disrupt a baby’s sleep. These leaps can cause unsettlement, crying, and sleep regression (Rijt and Plooijt, 2017).
3.2. Physical Discomfort
Babies might cry due to being too hot, too cold, hungry, or needing a diaper change.
3.3. Environmental Factors
Noise, light, or an uncomfortable sleep environment can also disturb a baby’s sleep.
4. What to Do When Your Baby Cries in Their Sleep
When your baby cries, observe before intervening. They may resettle on their own.
4.1. The Wait-and-See Approach
Give your baby a few moments to see if they can drift back to sleep independently.
4.2. Assessing the Cry
If the cry is urgent, check if the baby is too hot, cold, hungry, or needs a diaper change.
4.3. Minimizing Disturbance
Keep disturbances minimal and the atmosphere calm. This reinforces the idea that nighttime is for sleeping.
5. Soothing Techniques for a Crying Baby
Effective soothing techniques can help calm a crying baby and promote better sleep.
5.1. Swaddling

Remember to take care of your own well-being. If you are feeling overwhelmed or anxious, seek support from healthcare professionals or support groups.
8. Understanding Sleep Regression
Sleep regression involves a period where a baby who has been sleeping well suddenly starts waking up at night or refusing to nap.
8.1. Common Regression Periods
Common sleep regression periods occur around 4 months, 6 months, 8-10 months, and 12 months.
8.2. Causes of Sleep Regression
