How about making a scrapbook together? Is she crafty? I'm not LOL... or even more creative making furniture, like a picture frame and decorate it... Better Homes & Gardens has some great & easy ideas for that. I would love to do a mosaic table.

We play music together, a jazz like thing & give Matilda some drum gear to play along. or percussion.

Card games, like pincoccle or lollie poker...
