it's rare up here unless your kids are spaced way apart. My family had one for my mom when she had my little sis, which was 8 years after me. Sometimes i'll hear about a small group of friends getting together to do a mini shower for a close friend but not a full on shower.
They're not common here unless it's been around 5+ years since your last baby. While I do wish that you had a shower for every baby (just because they're fun, not even for presents), I do feel, and it is thought of here to be very tacky. I know DH's aunt is about 3 hours south and she doesn't understand this at all, there they have a shower for every baby.
