Wow, that can be tough. But you know what, this is a curve ball that has been thrown in your direction and just something you guys are going to have to throw all your heart mind and strength into...
Aspergers (or Autism) is definitely something that can be managed, but yes, you'll just have to learn routine... Might be tough for you guys but will be great for your son!!
From a father to a father, I know you'll do whatever it takes to provide the best for your kids that you can :D
