Hi, I have a 5-year old who just started school (in the middle of my chemo treatments). I think kids are very resilient and he seems to take it in his stride. He's never keen to visit me in hospital but we've been pretty honest with him about what's happening (while keeping him away from it all).
I've found that the thing with having a young kid is it keeps you pretty distracted. I feel like I haven't had time to wallow around and feel sorry for myself and its made me get up off the couch, take him to the park, that sort of thing. I also think it has given me motivation to beat this thing - I want to be around to see him grow up - and I think this has given me a really positive attitude to recover and get through all the treatments.
There's a few decisions I made (such as doing the cold-capping) which I did for him. I decided it would make this seem more 'normal' if I could avoid hair loss and that sort of thing.
Hope my experience helps. Anne
