You can find fun learning computer games they can play alone or with a parent... art projects-we recently just did one where we found lots of fall leaves in different colors/shapes then drew a tree trunk on paper and glued all the leaves on the page and we also painted the really small pumpkins... you can also do a "read-a-thon" ... just some suggestions that will maybe help!?

Here's a recipe for Bathtub finger paints - it's easy to make and the kids clean the bath tub without even knowing it!!!

2 Tablespoons liquid soap
1 Tablespoon cornstarch
drop of food coloring

Mix ingredients together for each color. Covered mixture with last for a few weeks.

My kids love to read and be read to, word searches, dot to dot, Lego's, water colors, mazes and crafts.  They also have AWESOME imaginations!  They can play for HOURS!  They love to make tents with chairs and play house, bank, doctor, store etc.  Good Luck!  I hope they feel better soon!

Thank goodness for SavvyShopperDeals!  I love being prepared for whatever comes my way (hopefully just hungry and sometimes dirty kids! )
