As far as diet goes I'm generally going with the flow and being a little bit flexible. It's common for chemo to have an effect on taste buds and appetite, so I cut her some slack there. She's often too sick to eat during chemo rounds so to an extent I let her eat whatever she wants when she is up to it, but I always offer healthy food as well as random things she requests. She's under the care of a dietitian at the cancer centre and they say that I'm doing the right thing. It's about getting calories in and if she's totally off her food we try to find what she can stomach. At the moment she's into porridge, raw apples, rice crackers, Milo with milk, spaghetti bolognese and cheese sandwiches. She also picks vegetables off my dinner plate but isn't so keen on them if she has her own plate (weird).
I also like to get her out for a walk if she's up to it and the weather permits. Everything I read says that light activity is a good thing so I encourage her to walk when she can, but I always have the pram with us so that she can rest.
