I went through four or five months of chemo, too, and lost all of my hair. It was hard to look and feel that way, even as an adult Mom. It's even harder for youngsters. People with young children have it tough, too, so I agree that any help you can offer for children is great. And small meals that are freezable are great, too (unless, perhaps, someone is a picky food person).
Another woman I knew who'd gone through it before me bought me some nice, warm hats, and I bought myself some soft cotton head lovies because your head actually hurts when you lose your hair and wearing a wig makes it sore, too, so it's nice to come home to something soft. In the winter, your head gets cold, too. (Hospital gift stores usually sell them, especially hospitals that provide cancer care. Found a link, here they call them Sleep Caps, but they're along the same lines of what I'm talking about.

But another thing I'm thinking of for these two, if you're up for it, is something my daughter makes for around $30. It's those no-sew blankets that are super easy to make, but so heartfelt a gift, and really, really great when you're feeling like crap a day or two after chemo, and you just need to rest. Having one of these makes you feel like your wrapped up in love.
We like to make them big, so feet aren't sticking out, so measure accordingly. Bigger is better. And when you go into a fabric store like Joann's, there are so many cute themes and patterns to choose from. Pick something you think that person will like.
Here's a good tutorial if you're unfamiliar with how to make them. i am not very crafty, but even I can do one of these. DD's done a lot now and can knock a big one off in a couple of hours. The one she made me is one of my favorite things ever, and I use it daily.
You are a kind-hearted person for even thinking of doing this. Thank you.
