Hello! We're picking up our new baby boy soon and have a 7 hour drive from South Carolina to DC! He will be 9 weeks when we get him. My biggest concern is potty breaks. He will only have had his 6 and 9 week shots and don't want him exposed to nasty stuff on the ground. Where would be the best places to let him go out and potty? We will be bringing a crate and a lot of potty pads and towels. What places would be the safest to let him out to potty? Any ideas? Thank you in advance!
