It's always great when a cancer survivor has a kid. Being a survivor myself I know how chemo and radiation can mess up your sperm. I had to go to a sperm bank myself. One of the most awkward experiences of my life. Fortunately, my wife became pregnant after chemo by "accident" so it's all good.
Anyways, congrats to you Andrew. Looks like your little guys were able to swim. Haha. Had to do it.
