Flying with a baby?

Amanda

I'm a FTM and have only flown once before so I'm kind of inexperienced with the whole thing. My baby will be 6 weeks going on 7 weeks old and I have no idea how to prepare. I'm breastfeeding but I don't like breastfeeding in public so would it be smart to take my frozen milk with me? I'm so stressed out and we haven't even bought the ticket yet. It'll be with southwest...if that matters. The flight is 1.5 hours but I'll be there for a week.
