My grandma would put her gold wedding band on a string and what ever direction it would spin would determine if it was a boy or girl... I also dont remember what direction was what sex.
With my first 4 my nose got wider while pregnant ( thankfully went back to normal after having them!) With #5 my mom said right away that it was a girl because it was the first time my nose didn't widden... she was right, it was my only girl.
I couldnt go by how high the baby was sitting... with #1 he was so high he was right below my breast. #2 was all middle.. straight out. #3 was so low after 6 months I had to lay on my side, I couldn't sit down or he was on my legs and they fell asleep with in minutes. It was fun thou listening to everyone guess ( I didn't know the sex either) then finding out at the end who was right and who was wrong.
