T.N.
I have learned with my kids that sometimes especially at 2 years old big birthday parties are that important. Since you don't have a lot of money to spare invite family to your home and have ice cream and cake. Depending on when the birthday is go to a park and have hotdogs or hamburgers and chips and sing happy birthday there. If you are not so much worried about having her family there and if she is in school bring a cake and goodies there, I think most schools would allow that. I enjoy planning parties so if I could help more let me know.
