I explained to my kids about what had happened in Japan and how there were children there who didn't have houses and some didn't have families. For family night we went through our closets and pantry and found things that the kids might enjoy. Most of these items I got cheaply (and some for free) using coupons and hitting sales.
Here are some the things that Sleepy Time Gal suggested:
- hand sanitizer
- shippable foods
- children's clothing and shoes
