I had a vivid dream that the baby was a girl. Actually, her girl parts weren't on display in the dream, but she was born already and known to be a girl.
In the beginning of the dream she was brand new, still slimed up and lying on top of me. I couldn't see her face, just the top of her head and her tiny naked body. Then somehow we were at my dad's house in the de facto "guest room" which had two twin beds. The Hottest Computer Scientist in the Universe got up and went to another room, and I picked the baby up and tried to feed her - but she wasn't biting (metaphorically). I started thinking about what I've read about breastfeeding and considering what to do to convince her, but then a bunch of people showed up to visit "the baby" and I felt really frustrated that we were interrupted and worried that she was hungry. :(
When I told my dad the next day, he said "Sorry to disappoint you, but it's a boy." Everyone is totally sure this baby is a boy, so much so that we sort of tend to believe them. Cuz we hear it every day.
