My 8 year old step daughter was right, she kept saying he was a boy, and he is. :) he could just really want a baby sister, as well. We never know :)
Yes, before I found out I was pregnant my 2 year old started saying I had a Lizard in my Tummy. Once I started showing a little at 12 weeks he started calling my Tummy Deon. I found out the sex at 16 weeks and its a Boy. He knew everything from the beginning.
