I wasn't sure where to put this?

I am going to ask my doctor, but I don't see her for another 2 weeks.

I have been trying to plan a trip to BC for our annual holiday after LO gets here. I'm hoping around 6ish weeks I will feel good enough to take about a 8 hour drive. I realize it will probably take longer because of stops for feeding and changes and whatever else.

However, I just heard from my MIL that she heard from someone else that travelling with newborns is a lot different "now a days" and you have to stop every 20 minutes or so and take them out of the car seat so they can stretch out?"

Has anyone else heard this? I have never heard this before and just wanted to know if our 8-ish hour drive is going to turn into a 24 hour thing....
