Mum's journey - she'll be having breast cancer surgery soon. What can I add to my care package that will help her post surgery?

Hi. 
my mum has been diagnosed with aggressive breast cancer and is due to have the lump and surrounding tissue removed within the next couple of weeks. Please could anyone advise me on anything that might help her after surgery? I’m going to order her a heart shaped support cushion and a sleep wedge. 
I was also thinking:

soft blanket 

grip slippers 

button up pyjamas 

natural camomile or lavender body wash.

sleep pillow spray

water bottle with straw

ginger sweets. 

Any other suggestions would be really appreciated. 

Thank you,

Christina
