Steve, great news mate!
My mother passed away 6 years ago now. Cancer. Mean shit.
I was glad to read that you are having those 3 month checkups and I would suggest NOT missing them and possibly changing them to every 2 months. Can be expensive, but the end result of course is worth it.
Spend as much time with him as you can, your son too. I think you guys will have alot of good times ahead of you!
Cheers!
