Flying with a baby?? 3 months old...

Ashley
I'm currently in a little of a dilemma. My aunt is slowly fading, and brought hospice in. I have to fly out with my mom because she never flys and feels very uncomfortable flying. Is it out of the question to take my 3 month old? And how bad is the pressure in their tiny ears? My husband is very much against her flying. So my only choice is go against my husband's wishes, or take my pump and pump and dump the next 4 days. What to do???
