Does she need you next to her to do activities? Does she get into imaginary play b/c maybe just a sheet over a chair could spark her imagination and she would take it from there. We have dress up clothes for our DD (27 mths) and stuffed animals, dolls, puzzles, books, etc. I am sure what I am citing is nothing new and you probably have all the above mentioned. I am a SAHM too, but we don't plan the day. We let her play with whatever peaks her interest. Some days it is dress up clothes and dancing around. Other days it is puzzles and books. Here lately she has miniature imaginary friends she carts around with her. She also has two big dogs as playmates so that helps.
As for TV, it is a hard one. Once you open that door it is a hard one to close. My DD gets to watch DVDs in the car when we are out on errands, but not in the house. I know it is cop out, but it works for us and keeps her searching out other things to play with. We do have computer games that she plays but she has to come ask us to play them and that might happen 3 or 4 times a week.
