Death, traveling with a toddler

Hey guys, I need some advice. I’m not sure what to do. My grandma passed away this morning, I was not really close to her but she’s my grandma non the less. We live in Ohio and they are taking her down to Kentucky for the funeral(that’s where my family is from). That’s close to a 6 hour drive one way. I’m not sure what to do. I’ve never drove that long with my toddler in the car she almost 2. I want to go, but I’m nervous about taking her for that long of a drive. If this was my mom or immediate family. Of course i would just take her no questions asked. I want to go just to be support for my mother.
