travel with infant 8 months old on plane

completely safe. Use earmuffs while takeoff and landing. Feed (latching or bottle) during takeoff and landing because the sucking will reduce any ear pain that occurs due to pressure differences. but in case your baby is sleeping do not wake up the baby to put in ear muffs or to feed

no it won’t. even newborns can fly without issue
