Death in the family

I had a death in my family earlier this week. The services are tomorrow and Monday. My dad just called me and told me the my 3 week old can't go. She's only breastfed and very colicky at the moment. I understand why she shouldn't be there but I am beside myself that she can't go. What if she needs to eat while I'm there. I have no idea how to deal with this at the moment.
