Any other August mommy’s getting ready to evacuate from Marco/Laura? Any tips for a long trip with a 3 week old?

After Harvey, we aren’t taking any chances. My SO has to stay since he’s a cop so I’m headed to my hometown (30 mins away) and leaving with my fam later today or tomorrow. My 3 weeks postpartum appointment was supposed to be tomorrow but I doubt I’ll make it. Blaaaah.
