Thoughts are with you at this time, I read your post from start to finish staying up late well past the bedtime and please know that I wish you both all the best, decisions are always hard to make but know that whatever decision you make it will be made from your heart with the best interest for your love of Kal.
I am from your area and know of Russell Mitten and he is highly recommended but ultimately you know best and what Kal can cope with, I hope you have many more wonderful memories together.
