Motion sickness can begin to affect infants during car rides as they grow. To help relieve symptoms, try keeping the baby's gaze engaged with toys or play rather than having them stare at a stationary object outside the window, which can exacerbate nausea. Keeping the car seat positioned in the middle or front (if safe and in an SUV) and ensuring there is at least a one-hour gap between their last milk feed and the journey can make a big difference. For persistent cases, consult your pediatrician, who may be able to recommend age-appropriate, safe medications for travel nausea.
