Advice on moving towards more open adoption

I think if you agreed to provide a phone number you should have one that actually works when she calls it. Whether its your cell or your pre-paid phone. How would she get in touch to tell you where to send updates if they have to move? With regard to the privacy thing perhaps your husband might benefit from some books on adoption and relationships with birth families (I don't mean that in flip way). I got my in laws, "What Adoptee Wish Their Adoptive Parents Knew," and it was very enlightening for them about trying to forge a relationship with birth parents. I think for them wanting to limit that birth family relationship was about claiming DD and being afraid of losing her.
