Flying with Baby

Ny`Shalah

Hello mommies. So our daughter is gonna ride an airplane for the first time next month. She will be four months at the time of the flight. We are flying to San Diego and it will be a five-hour non-stop flight for us. I have quite a few questions:

1) How can my husband and I keep her calm during the flight?

2) Does nursing during takeoff really help keep babies ears from popping?

3) Can I take breast milk and my breast pump on the plane?

My husband and I have flown MANY times before, however this will be our FIRST time ever flying with our baby girl and we are first-time parents so this is all new for us.
