RELAXXXXXXXXXXXXXXXXXXXXXXXXXX, don't go overboard, this is her first birthday and she won't know what all the excitement is about. . .but just know it's hard to go "down" in Birthday celebrations. Each year you will wreck your nerves trying to do the birthday better than you did the year before.
For a first birthday, usually a quiet dinner party with a cake is plenty for a one year old. . .too much excitement (jumper, clowns, Chuck E Cheese) is overwhelming for a one year old; and believe m; your relatives will enjoy the party more than your daughter.
In this day and age Birthday Parties are EXPENSIVE, and unless you are looking for a $500.00 event each year, I would think small, or at least something that is manageable. There are plenty of time for the more elaborate parties. . .but just know if you start doing these parties while they are small, it will be hard to stop later. My six year old, now plans her next party at the present year party (whew). . .Some ideas are Chuck E Cheese, The Jungle, Fairyland, Pixieland, Jelly Belly Factory, Build a Bear Workshop, area park (my daughter's birthday is in Feb, thus it's hard to plan out door activities) Bay Area Children's Museum; McDonald’s. . .but keep in mind all of these ideas are expensive.
I would love to hear from other parents on idea’s as it’s no joke to plan a party without taking out a new mortgage.
