Boy or Girl? Can we choose?

We are open to any race. We have been waiting for foster care placements with no luck. We have been told that homes are needed for teens, but have choosen not to take teens. I don't think it would be good for our boys age 8 and 4. I would like to clarify: If we went with newborn adoption, we wouldn't be matched with expecting moms. Sonagrams are not 100% accurate. We would have to wait until the agency had a mom and baby that were not matched with a family and had just considered an adoption plan. This may be a long wait. The agency we considered had 4 "already born" babies last year. International adoption is not an option for us, because it is way to expensive. P.S. Our foster license is for any race, 1 or 2 girls, age 0-10, mild to moderate medical problems okay
