The first birthday is more for mommy and daddy, grammas and grampas, than for the baby. So just have a fun time, make a cupcake for baby and get some fab photos.
You know what your baby likes, so get some little thing, and you don't have to spend a fortune because the baby doesn't care and doesn't know the difference!! Let grandparents, aunts and uncles get some gifts.
The 2nd or 3rd birthdays are when it gets to be really fun, and they understand a little better what's going on.
Keep #1 simple and fun, don't go overboard, and she will enjoy her cupcake and tearing the wrapping off a couple presents. Don't be surprised if she wants to play with the boxes, ribbons, bows, and paper more than the presents!! And get pics of that too!!
