Outside Activities - playing in the dirt / Frisbee / Jumping Rope / Sidewalk Chalk / Gardening / Flying Kites / Going to the park to kick around a soccer ball or something like that / Camping in your backyard or at a park / Going fishing or swimming
Inside Activities outside of your Home - Library / Walk around the mall window shopping / Movie theater / Bowling / Volunteering
Inside Activities inside your home - Scrapbooking / Painting / Reading / Movie Nights / Pajama days (where you wear your pjs and bum around the house all day - this may be more fun for YOU than her!) / Tye-dye tshirts / Puffy paint on shirts/shoes/etc / Craft projects / Needlepoint, cross-stitch / Board Games / Computer fun - playing games, learning how to type, going online to play games and look stuff up), Writing letters and sending them to family / friends / Cooking day - let her choose the food and help you make it / Baking day - same thing but with sweets!! "Switch" Day - you are the kid and she is the mom. She gets to make and choose dinner, sleep in your bed, tell you what to do all day.
Hope these ideas help!
