Hey Ryan, some couples try to have children and can't. You and Ginny have been blessed so far there's no reason why it wouldn't continue.
I've got 5 children, the last one, Helene was born at 24 weeks...that was 29 years ago on the 20th of January. She weighed 1.5 pounds. Considered almost a lost cause back then at that age. This was at the Royal Victoria Hospital in Montreal. My wife and I were at the hospital til Helene was able to leave. I slept there for 2 months. There were a lot of other children in the same neo-natal care unit and lots didn't make it for a bunch of reasons. The biggest reason I think was that some parents would just visit the child once in a while for 30 minutes or and hour. You have to stay with them! Put the gown on, stick your hands in the incubator, touch them and talk to them. Sounds suckie I know but I believe that. I can speak volumes on this stuff but this is not the place to do it.
Good luck to you and Ginny.
