Traveling long distance help!

Sabrina

Parents of multiple children semi close in age please help me I need advise! So I have 2 almost 3 year old and I’m about to have one February 3rd and we r currently preparing to move in mid March! So the new baby will be about 6 weeks old and the car ride is from NC to NY I was wondering where should the car seats be placed? I plan on sitting in the back anyway with the two of them but I read the middle is a good option for the infant seat? Is that correct? Also anyone who travels with small kids plz help me I need advise on how to do this so I Dnt lose my mind in a car for 8/9 hours! Tia!
