At 2 months old, "entertainment" on a plane in 2026 is less about toys and more about sensory comfort and basic engagement. Since their vision is still developing, high-contrast (black and white) cards or soft books are highly effective at holding their attention for short bursts. However, the best "entertainment" is usually the parent’s face; simple singing, talking in a soothing voice, and gentle "finger play" provide the social interaction they crave. Practically, the focus should be on managing the environment: use a baby carrier (like an Ergobaby) for hands-free pacing in the aisle, and ensure you have a "sensory bag" with familiar-smelling items to provide a sense of security. Since babies this age sleep for 14-17 hours a day, the most successful strategy is to feed them during takeoff and landing to help with ear pressure and then use the white noise of the engines to induce a long nap in a travel bassinet.
