N.; there is not right or wrong as to who is supposed to throw a baby shower, its great that you want to, and im sure you will be invited to the other parties, if you wish, its nice to have more than one shower, its great she is gettting three, are they all before the baby comes? is there one after it is born? before and after showers are great, before you get stuff like needs, bottles, blankets, etc, after you get more clothes, and its ok to give her more, its totally fine, have you asked her what she wants? and its ok to have repeat freinds and family if they so desire to come, some may not , and they may need your help with another one too, maybe you can offer to help out, but it is ok to throw another, and its ok to not to as well, to throw one just because you think you have a right, does not always go over well, do things out of love not cause you are supposed to do it, not everyone has a sister, or the person who is supposed to do it, so ive not heard of the supposed to do it person . just be happy and dont get offended if you dont get to, you can always get her things that will still mean alot to her, we are greatful for the person who threw the shower but we are also greatful to the people bringing gifts, if you are getting offended then you are in the wrong mind set, if you want to throw her another one, make it last, so you can find out what she really needs, and get that, either way have fun and enjoy life, or you can help and attend all of them and really be a good supporter, D. s
