Jeff, thanks for sharing your experience. We would actually prefer the older end but didn't want to rule out sib groups with one older/one younger. We have run into that "prejudice" also...but in our situation our DD is the baby of the family (8 cousins, next youngest is 10yo) and would be more displaced by having a younger child come in.
If only we'd known the questions to ask about interstate at the beginnning.
We are giving it a year at this agency then switching in order to "fish the larger pool" so to speak. I try not to look at the national photolistings because there are so many kids I'd love to inquire on and can't.
