How do I get health insurance for a child that provides coverage in both california and washington?

We share custody and so she lives in two states and we need her protected in both, but are unable to purchase seperate insurance because they won't insure her if she already holds insurance in another state....

You can have more than one policy. Both parents should have an insurance policy for their child. The primary custodial parent ( the parent the child lives with most of the time), is the primary card holder, the secondary is the other parent.
