My wife and I had a lot of difficulty becoming parents. We had multiple miscarriages and ended up going the IVF route. When this finally, worked, our little girl was born at 25 weeks and 5 days and 1lbs and 14.5oz.
As such, when we wanted another child, we were very interested in going the adoption route. We had our concerns including but not limited to would we feel the same about our adopted child as we did our daughter, what is the family medical history like, would the baby be healthy, will the baby ever want to leave us and go back to their birth parents when they get older?
