mom angry I won't travel with 2.5 month old?!

Amanda
So my mom has a lot of health and mental issues so she has trouble thinking logically sometimes or seeing someone else's perspective. When I found out I was pregnant and due Oct 3rd I tried to prepare her in advance that I would not be able to visit her for Christmas. It would require flying (which not sure if baby will be totally vaxed yet and we can't afford) or driving which without a baby takes 16 hours and I'm guessing with a baby would take much longer. She is furious and told me I'm selfish and she no longer considers me family. Am I way off base thinking traveling that far with a 2.5 month old is a bad idea/near impossible?!
