Sleep Problems and Changes

Baby wakes every hour

Baby wakes every hour

Why a baby may wake every hour Infant sleep is biologically different from adult sleep. Babies spend substantial time in active sleep, a lighter phase that may include facial movements, brief vocalizations, limb movements, and irregular breathing. They may appear awake even when they have not fully emerged from sleep. As one sleep cycle ends, […]

Common baby sleep problems

What normal baby sleep looks like Infant sleep is distributed differently from adult sleep. Newborns commonly sleep in several short episodes across day and night because their circadian rhythm and sleep-wake regulation are still developing. They also need frequent feeds, and some babies wake during the night because they are hungry. A young infant may […]

Baby fights sleep

Baby fights sleep

Why a tired baby may fight sleep Infant sleep is biologically different from adult sleep. Newborns have an immature circadian rhythm, meaning their internal timing system has not yet reliably synchronized sleep and wakefulness with the day-night cycle. Sleep is also distributed across multiple periods, and infants commonly transition through lighter sleep before entering deeper […]

Baby only sleeps when held

Baby only sleeps when held

Why babies often sleep better when held Holding offers several cues that help an immature nervous system settle. A caregiver’s body provides warmth, rhythmic movement, gentle pressure, familiar scent, and auditory input such as breathing and a heartbeat. These cues can reduce the abrupt sensory change that occurs when a baby is placed on a […]

Sleep Changes After Vaccinations

Sleep Changes After Vaccinations

Why Vaccination Can Change Infant Sleep Vaccines activate the immune system by presenting antigens that train immune cells to recognize a pathogen or a component of it. This process can involve cytokines and other inflammatory mediators. Those signals may contribute to transient fatigue, reduced activity, mild fever, or a greater need for sleep. For some […]

Baby Sleep During Nasal Congestion

Baby Sleep During Nasal Congestion

Why Nasal Congestion Disrupts Baby Sleep Infants have small nasal passages, and their nasal breathing pattern makes obstruction more consequential than it may be for an older child or adult. Mucosal swelling and thicker secretions can increase airway resistance. A baby may then wake repeatedly, breathe noisily, pause during sucking to breathe, or become frustrated […]

How teething illness and travel affect sleep

How teething illness and travel affect sleep

Teething and the perception of poor sleep Teething is a normal developmental process in which primary teeth move through the gingiva. Local inflammation may cause tender gums, increased chewing, drooling, irritability, and a temporary preference for softer or cooler foods. These sensations can make settling more difficult, particularly when a baby is tired and has […]

How to fix baby sleep issues

How to fix baby sleep issues

Understand what normal infant sleep looks like Infant sleep is distributed differently from adult sleep. Babies move through shorter sleep cycles and may partially awaken between them. A young infant may wake to feed several times overnight, while older babies can still wake because of teething discomfort, illness, developmental changes, separation anxiety, or a need […]
