I thought we can share our experiences at other showers. Something we liked, that was different, odd. I'll start!
I've been to two baby showers where they omitted the gift opening portion. One shower was a traditional women only shower. Basically there was food and everyone said some encouraging words to the mom-to-be. That was it for three hours. The gift table remained untouched. They also passed around a "chore sheet" where you sign up to clean, run errands, or cook. And when you signed up to cook it was for four adults and two children!
The other shower was a co-ed bbq (which I loved!). The mom-to-be opened some gifts at her leisure but all of the guests attention was never on her. I personally get bored after about the 5th gift as do many others who start to carry on side conversations.
