2nd Baby Shower; Is it appropriate?

I was thinking about this so much because my sister once offered throwing a baby shower for the second child this coming August maybe. I was okay about it at first but now when I think about it, I don't feel right. Isn't that a bit TACKY? Won't the guests feel like I have all the things I need and probably more? (I still have the same friends and family who have attended the first shower) Won't they think I am being GREEDY??? I personally don't feel right about it so I'd better turn down my sister's offer. Of course, gift giving or a simple gathering to celebrate the new life is very much accepted (if anyone will give).

I was reading a lot of online forums about this question and usually people would say a second shower is acceptable only if the kids are more than 5 years apart, of different sexes, should be a smaller party than the first one. I had a boy and now I am having another boy, 3 years apart. Most of the things are still in good condition and its greedy to be asking for another shower. In the end, I believe that all babies deserve to be welcomed into the world with a celebration may it be big or small. Whether you have a baby shower, a blessing, a welcoming or baby naming, it’s still a celebration of new life. In my case, I will opt not to have a second shower but I'd just throw one big celebration and welcoming of life by with his Baptism. I am sure his Ninong's and Ninang's with surely give him a little something then.
