Please don't make the first birthday party a big deal! she won't remember it and it's more for you than her. she just wants a small crowd of her favorite people (maybe 20 at most), not all asking for her attention at the same time which will make for a cranky birthday girl. add a light meal, a cake, some drinks, balloons, and you are done. save the big event for when she will appreciate it!
