Baby Shower for #2?

Kate

Have any of you that are having or have had a second, third, etc.. baby had another shower? I am pregnant with my 2nd child which is the same sex as my first so we have most of the things we need for him. I also don't have many friends since I am a stay at home mom. I thought of doing a get together like pot luck and everyone brings diapers and if they like they can bring a gift. Would it be tacky to throw something for myself like that?
