I've organised many a shower, most of them ridiculously alcoholic.
Over here things are very Americanised and Baby Showers are the norm, however none of us are into the cutsey, game playing, guess what's in the baby jar bollocks that go along with it.
The one we had this past weekend for our friend, was an all-you-can-eat brunch, and a chance for everyone to catch up before her baby girl is born. Just a few balloons. She and her husband registered at a local baby store, but only for minimally priced things like teething rings etc. and we love her so we spoil her.
We're a mixed bunch of Brits, Aussies, Americans and Irish so none of us are really into the over the top showers like some I've been to.
One of them, I myself was 6 months pregnant, and had to spend 45 minutes (I shit you not) along with 45 other people (!!) watching a and friend (but not super close) open a mountain of gifts, some of which were absurdly expensive (stroller, $700 crib, baby swing, car seat, breast pump etc) and I didn't even get a thank you! Along with this came playing utterly crap games (nobody could say "baby" or you lost a clothes peg?) and other games like guess the food in the nappy. Thankfully I could pass on that game but watching other people play was just tedious. I got my revenge by eating several pieces of cake and fuck load of food.
My own "baby shower" was myself and close friends, all getting discounted mani/pedis and then going for dinner. No registry or anything - and I had a fantastic time.
I get the "hate" for the ridiculous baby showers you see on TV, and I am totally opposed to baby showers for the second baby (meaning full registry for baby number 2 - what happened to all the shit we bought you the first time round???) but I love doing baby showers for my friends that mean we can all get together, eat cake and drink champagne and give our friend a fun time.
There are a number of us pregnant with our seconds, myself included and we'll do showers again, only no gifts or anything like that - just a good excuse to have a brunch or dinner with no stress.
So I guess it depends on the definition of "shower" - a chance to spoil a friend and give small tokens for the baby/mum = yes, a huge overblown affair when the mum-to-be sits on a throne (yes we have those here), expecting all her friends to pay for all the shit she needs to have her baby whilst having people play stupid ass games = no.
I am very firmly in the first option camp.
