Is it proper for the mother of the groom to give the bride ashower or even help?

I think that it is more usual for some friends of the bride or groom's parents to host a shower or some of the bride's girlfriends but it is not improper for the groom's mother to host one if she would like. If there are other showers being given, I would not do another one if I were the groom's mother. It is nice to have the groom's mother and the bride's mother just enjoy the showers as guests.
