playhousedisney.com has a "celebration center" page with free stuff you can print and lots of ideas. For cake, try cupcakes or fun shaped mini cakes (Reynolds makes them - look in the cake mix section). Dollar store has lots of cheap decorations and partyfavors - even in Mickey and Pooh! As far as etiquitte - I would only invite one or two small children... 1 year olds don't really get the idea of the party anyway, this is for Mom! :-) A parent should stay with their child during the party, and be prepared to feed everyone, even if it's just a snack. For my DS's first, we did pinwheel sandwiches, fruit, and veggies, and punch. After eating, we did presents, then cake. Pretty low key, no games or anything. It was great! Have fun!!!
