How many Baby Showers should one mother have?

Let's say you're pregnant with your second, third, fourth child. Do you believe it is acceptable to have/throw multiple Baby Showers (assuming only 1 per baby)?

Personally, I can understand a few different perspectives on this.

For one, I believe that a baby shower is a celebration of that baby; of a new life being born into the world. Every baby, every life, deserves to be celebrated. Therefore, I can understand why one might throw a baby shower for each of their children.

On the other hand, I understand that many people use baby showers as an opportunity to get gifts and supplies for their babies. And that many people feel that you "shouldn't" attend a shower without a gift. So because of that, I can also see why somebody might feel that you should only have a shower for your first born or maybe only for your first *few* children. Maybe they feel it's "tacky" to have more than 1 or 2 showers.

Anyway, I'd like to know what you think. At what point should someone stop throwing Baby Showers for their unborn children? How many showers have/will you have?
