With DS (my first baby), I remember when I was around 12 weeks I had a dream and woke up the next day certain he was a boy. The funny thing is, the dream wasn't about babies or me being pregnant or being in labour or anything like that. I can't remember what it was about, but I woke up the next day just knowing that I was having a boy. I was right of course, but didn't find out until he was born. The next two I had no gender dreams - I was uncertain with DD1 right up until she was born. DD2 I was sure was a boy until the ultrasound showed otherwise!
