7 hour drive with 3 month old?

M

So my husband is traveling for a work conference in October. Baby will be around 3 months. I don't care if he goes but he is pushing me to come and of course bring the baby. He is making it into a road trip and wants to stop along the way. I'm a ftm and I pretty much said no it sounds miserable being in a car that long with a baby. I will be breastfeeding we will have to stop for feedings and changes. When I mentioned this to a friend she seemed to think I should go, so now I'm wondering what other moms would do. Not to mention he will be working so I'll be alone with a baby most of the day.
