A two hour flight is usually fine for a healthy two month old once your paediatrician has cleared the usual newborn check-ups. The ear discomfort during takeoff and landing comes from pressure change. Offering a feed during climb and descent is what helps, not how much your baby actually drinks.
Next Steps
Put your baby to the breast, bottle or a pacifier as the plane climbs and again as it descends. Keep your baby upright and well hydrated through the flight. If a check-up or vaccination is due around the travel date, mention it to your paediatrician beforehand.
Health Tips
Stroller choice and timing is best decided with your paediatrician, since it depends on your baby's growth. See a doctor the same day if your baby develops fever, breathing trouble, or refuses feeds completely.
