6 hour car ride with baby

Whitney

So I was invited to go on a beach trip with some of my family the week of July 4th (baby will be 15 weeks) but it’s a 6 hour car ride. He is exclusively breastfed and eats every 2 hours, not to mention after he eats the last thing he wants to do is get back in his car seat so that would delay things even more. My husband won’t be able to go so If we do go I’ll be on my own for most of it, just not sure if it’s worth going. Anyone road trip with baby and have success?
