Our 13 yr old is visiting grandparents in another state and as timing will so often go, her biomom "found" her through myspace. past history of biomom not good, i'm not gonna slam her let's just say her own mom won't have anything to do with her at all. we have kept in touch with biograndma.
i guess the emails started out as "ask your mom who i am?" then they went to "i am your real mom" "i want to meet you" our 13 yr old of course is confused, upset and angry with me.
adoption has been a part of all our children's vocabulary since they were brought home. we have told all of them that when they turned 18 we would not stand in their way of looking for their bios. in fact, growing up our oldest kept telling us as soon as he was 18 he would find his biomom well he's 24 and hasn't looked at all.
is there any advice? we don't want to talk negatively of this woman but we do feel she has jumped the gun and not waited till our daughter turns 18 (5 years away!). our daughter of course wants to meet her other family but it really is not a safe situation and we are concerned once she gets back home from her summer visit the pressure will be on.
