The guest book was a children's book that the ladies signed and added comments. We had a short quiz asking who (mom or dad) would most likely do various simple things. The ladies "decorated" newborn disposable diapers with notes to encourage the mom and dad when changing baby. We had brunch and then later cake and pie. Mom-to-be opened the gifts and we all enjoyed commenting on them.
It was a fun morning with the ladies and I think we managed to "shower" the couple with love and gifts.
