I'm in the same situation as you! My son's bday party is May 12th and I'm a SAHM and my fiance isn't making very much money right now. We're doing a jungle theme and having the party in our backyard. I'm ordering all the plates off Oriental Trading and I bought plain colored napkins, cups and lots of green balloons at Walmart. I asked my aunt and my grandma if we could borrow their patio sets so everyone will have somewhere to sit and then I asked all my family to make something. We're doing finger sandwiches, fruit salad, and possibly hotdogs. I'm making some "hard" lemonade for the adults to enjoy and having punch/soda for the kids. My best friend is making the monkey-shaped cake. You could make your own cake..they're pretty easy. If you make a large sheet cake, you can carve it into a fun shape and then icing it is a breeze (no fancy drawing to do). Something simple would be a beach theme and then have a beach ball cake...make a round cake and ice it in different colored sections, like a beach ball. She's also making a little tiny banana cake just for my son so he can go to town and not ruin the entire cake. I'm not providing alot to do because at this age they're so easily amused anyway. I'm borrowing a good sized blow-up pool for the few kids that will be there and the adults can mix and mingle. Keeping the decorations to a minimum, asking family to contribute food or drinks, and making your own cake will save lots of money and then if no one has anything for you to borrow you might be able to afford something on your own.
