Our first road trip as a family

Well tonight we'll attempt our first real road trip. It's a 10 hr drive to Spencer/Sioux Falls. Jordan is getting married so we're headed his way there. I'm curious if Arridian will do ok w/ bottles for the road or if we'll be pulling over every 2 to 3 hrs for him to eat. I pumped so we have enough bottles for the way there and the way back just in case. Wish us luck.
