Hi,
good for you Martina(that's my daughters name too). I remember the days when I would make vegetables out of construction paper and pretend to make vegetable soup. Get her some shapes and playdo and we used to make our own (kids love to do that). If I find the recipe, I'll PM it to you. Go to the dollar store they have lots of crafty things cheap. Blocks and chalkboards are also fun. You can also get her some pre-k workbooks to get her ready for school. It doesn't have to be non-stop entertainment, just a few things through out the day. Good luck.
