Why Is My Baby Fussy at Night?
If your baby seems more unsettled in the evening hours, you’re not alone—and it’s not your fault. Many babies go through a phase of increased fussiness at night, often between two and twelve weeks old. This behaviour is normal, common, and usually temporary. Even well-fed, well-loved babies can be inconsolable during these hours, which can feel overwhelming when you’re already exhausted.
Here are some of the most common reasons babies are fussy at night:
-
Overtiredness — missed naps or late bedtimes can lead to overstimulation and difficulty winding down.
-
Digestive discomfort — gas, reflux, or immature digestion can cause crying or restlessness.
-
The “witching hour” — many babies experience a regular late-day crying period for no clear reason.
-
Cluster feeding — babies often feed more frequently in the evenings to boost milk supply or prepare for a longer stretch of sleep.
-
Underdeveloped self-soothing — newborns rely on external comfort and may need help calming their nervous system.
Your Baby Could Be Fussy At Night Because Of…
1. Overtiredness
Babies who don’t get enough daytime sleep or are kept up too long between naps can become overtired, which actually makes it harder for them to fall and stay asleep. Signs include frantic crying, arching their back, or appearing wired and unable to settle. A consistent nap schedule and earlier bedtime can make a big difference.
2. Digestive Discomfort
Newborn digestive systems are still developing. Gas, reflux, or milk sensitivity can lead to fussiness, especially when babies lie down after feeds. If your baby pulls their legs up, cries during or after feeds, or spits up frequently, digestive discomfort may be to blame. Try paced bottle feeding, upright burping, or holding baby upright after feeding to reduce symptoms. Talk to your doctor if symptoms persist.
3. The “Witching Hour”
Many babies go through a daily period—usually in the late afternoon or evening—when nothing seems to soothe them. This is often referred to as the “witching hour.” While there’s no single cause, it may be related to overstimulation, hunger, or adjusting circadian rhythms. This phase tends to peak around six weeks and resolves on its own by three to four months.
4. Cluster Feeding
It’s common for breastfed babies to want to feed more often in the evenings. This is called cluster feeding, and it helps increase milk supply and tank up before bedtime. While it can feel like your baby is constantly attached to you, this phase is temporary and usually resolves as feeding patterns regulate.
5. Underdeveloped Self-Soothing
Newborns are still learning how to manage their own emotions and reactions. They rely on your touch, voice, and presence to feel secure. Swaddling, rocking, skin-to-skin contact, or using a soother can help calm an overstimulated nervous system and promote sleep.
