True car sickness is rare in newborns. While uncommon, many parents still wonder about potential discomfort during car travel. This article explores the physiological reasons behind this rarity and offers practical advice to ensure comfortable journeys.
Understanding Motion Sickness in Infants
Motion sickness arises from a conflict between sensory inputs that help the brain understand body movement and position, including signals from the inner ear (vestibular system) and eyes. In older children and adults, a mismatch, such as seeing a stationary car interior while the inner ear detects motion, can lead to nausea.
However, a newborn’s sensory systems are still developing and are not yet fully integrated. The vestibular system, responsible for balance, continues maturing after birth and is not fully mature until adolescence. Similarly, a newborn’s visual processing is limited; their vision is blurry, and they cannot focus effectively. This immaturity means newborns are less likely to experience the sensory conflict that causes motion sickness.
Recognizing Potential Signs
While true motion sickness is uncommon, newborns may still exhibit signs of discomfort during car travel. These signs are often non-specific and can be difficult to distinguish from other common newborn issues like hunger, a wet diaper, reflux, or general overstimulation. Excessive fussiness, crying, or unusual pallor (paleness) could indicate general distress rather than car sickness specifically.
Newborns might also display increased salivation or spit up during car rides. While vomiting can be a sign of motion sickness in older individuals, spitting up is very common in healthy newborns due to their immature digestive systems, overfeeding, or swallowing air. The muscle at the entrance to their stomach (esophageal sphincter) is weaker, making it easier for contents to flow back up. Therefore, observed spitting up or crying during car travel does not definitively confirm car sickness, but rather suggests discomfort.
Ensuring Comfortable Travel
Several strategies can help make car travel more pleasant for newborns.
Car Seat Safety
Ensuring the car seat is properly installed and fitted is paramount. The harness straps should be snug at or below the baby’s shoulders, and the chest clip at armpit level, without bulky clothing underneath. The car seat should also be reclined at the correct angle to keep the newborn’s head back and airway open.
Environmental Comfort
Maintaining a comfortable temperature in the vehicle is important, as newborns do not regulate their body temperature effectively. Avoiding strong smells like perfumes or air fresheners is advisable, as a newborn’s sense of smell is highly sensitive. Ensuring the baby is not overdressed also helps prevent overheating and discomfort.
Travel Planning & Soothing
Planning for frequent stops, approximately every 1 to 1.5 hours, allows for feeding, diaper changes, and a break from the car seat. Soothing techniques such as offering a pacifier, playing gentle music, or having another adult interact with the baby can help. If parents have persistent concerns about their baby’s comfort or health during travel, consulting with a pediatrician is recommended.
