My husband is an owner-operator. We live in Idaho and are thinking about making a run east (West Virginia, Michigan, etc.) because my husband's father is not in good health.

My question is, how do we do this legally with a 21-month old daughter? We make local day runs with her and she does great! Of course, I'll be along to take care of her. I'm just wondering if anyone knows the laws for different states. For example, in Idaho it is legal for her to be in the sleeper or even on my lap in the passenger seat. Our truck is older so it doesn't have passenger air bags to worry about.
