Great ideas so far!
We have different tubs of stuff so that things can be put away and appear 'new' rather than all sitting around, seems to make it more exciting???
Craft - make some felt shapes/animals etc to make stories with
made people out of paper cups, decorated them and use for puppet shows
envelopes also a big hit - loves to draw and decorate and make letters to send to people
Pasting with cotton balls, patty pans - lots of household stuff
Playdough - cookie cutters etc
Pegs - Make a washing line inside at DD height and hang stuff on it with pegs (then folded etc) , we have played with pegs for hours (thanks to yiayia - who gave both girls a basket full of pegs)
Could you also make a small box of sand outside so she can dig etc in the space you have?
Perhaps a small planter of seeds - we planted some seeds recently and DD loves watering and watching it grow.
Grow potato people/alfalfa on the window ledge.
Baking - gotta be careful here as I eat it all!!!!
I think to you should be really realistic and use stuff like Playschool/DVD's to your advantage.
Can you get DH or DSD to take DD to the library or park in the pm or early am - this is so tricky when trying to manage work/school etc.
Whatever works!!!!!
