There are plenty of get well gift baskets on the market, but if you have the time you could create a personalized basket just for them to cheer them up and make them smile.
Any kind of container will do for the basket. You could choose a small laundry basket or plastic bin. Check the kids bedroom/storage area of a store like Target or Walmart for fun totes, baskets, etc.
First of all, let's think about food. There are plenty of healthy snacks that kids love like fruit snacks, crackers and granola bars. Fresh fruit and drink pouches could also be included. And if you really want to put a smile on their face, you could add their favorite candy!
Reading books and activity books make great gifts to put into the gift basket. A coloring book could keep them busy while they're stuck in bed. Don't forget the crayons if you go for this option.
Playdoh and clay make great activities for a sick child, especially as they have the time to put some thought to it (and can get some help from you). Some masterpieces can be created, in this time of illness, to put in a place of honor for all to see.
There are plenty of children's movies on DVD that you include in the gift basket. Or maybe a tabletop game like chess, mini monopoly or scrabble that you can play with your child while they are ill.
Last, but not least, don't forget the cuddly plush animal - an essential friend in the recovery process!
