On a long flight take a spare change of clothes for yourself.
When I’m packing for a flight, often the person I forget about is myself. However, I have learned that there is one thing I should not forget and that is a spare change of clothes for myself. It doesn’t take up much room in my hand luggage, it can be as simple as a pair of leggings and light top, but it is definitely worth remembering. Because if my baby accidentally spills food, vomits (or worse, and yes there can be worse) on me, I don’t have to travel the remaining 15 hours covered in gunk and I arrive at my destination looking semi-decent.
