We are the same. I haven't been anywhere for a fortnight. Thankfully my brother and his GF have been here, otherwise I would've gone insane by now..

helping put clothes away (or sorting them).
making then playing with playdough (but our DD spends a lot of time helping cook).
building with blocks

We also do crafts and painting (I got a box together after last time I was stuck in this position. You can build it up cheaply at Crazy Clarks and similar stores)..
