Travel overseas/flight with 2 months old

Ill be giving birth soon, and having plan to go to malaysia when baby is around 2 months+ and will be taking flight, for an event. Any mummies travelled with their newborn when theyre still very small. Can share tips and what to expect when travelling with newborn, esp when taking flights. And what should i bring along. Do i feed baby when taking off and landing, to reduce pressure on the ear? And how do you pump when travelling? #advicepls #firsttimemom
