Good for you! I felt the same way, that I was able to enlightem them on a topic they knew nothing about. When they told us several things they wanted to do, we told them no way, and believe it or not, they turned around and agreed and even changed the way they will do things moving forward after hearing our reasons etc. They even went on to tell us that we "paved the way for many kids, not just our own" by being so well researched and letting them know what we expected. I feel confident that with your persistence, it will pay off and you will come up with a solution you can all agree to! Good for you!
