Your child still needs rules . . .
She stated "If you spoil a child going through chemo, then you just have a bratty kid then they are done"
Of course, there will be LOTS of different rules when your child is going through chemo (If they can only keep chicken nuggets down, that's what they are going to eat.) But you should also have similar rules to what you had before your child got sick. If you never say no to your child that is going through treatment, imagine what it will be like to try and say no when they are done. . . Lets also not forget, there are other children at home.
Try and keep life as normal as possible when you can. Get out of bed, set time for school work, have a bed time. When life can be normal, it should be. Because Cancer certainly gives you a new sense of that word.
