Gender tests

My big anatomy ultrasound is coming up in a couple of weeks, and we're hoping to find out what this baby is. Our last two children were "surprises", but because it has been so long since we've had a newborn.... we have a lot of shopping to do! Unfortunately, there isn't very much gender neutral stuff available for purchase so finding out if this is a boy or girl will make things a lot easier.

I decided to try out a few of the Old Wive's Tales for gender prediction, and then we can see how well they worked for this little guy/girl!

You add your age at the time of conception and the number for the month you conceived.
~ If the sum is an even number - It might be a boy.
~ If the sum is an odd number - It might be a girl.
I was 30, and according to the due date calendar, we conceived around March 2nd... so 30 + 3 = 33. Odd = GIRL.

Another one states:
"This an easy baby gender prediction method to try. Take a pin, needle, or wedding ring and attach it to a thread or strand of hair. Hold the dangling item over mom to be's belly while she is lying down. If the needle or wedding ring swings in a strong circular motion, you will be having a girl. If it moves in a to and fro motion like a pendulum, you will be having a boy."

I tried this 3 times with a needle and embroidery thread, and all three times it swang in a circular motion, which means GIRL.

Another Old Wive's Tale claims that if the baby's heart rate is >145 bpm, it's a girl. <145 bpm, and it's a boy. This baby's heartrate has been 160-165 each time, which says, GIRL.

Have you heard of any other old wive's tale that predict whether a baby is a boy or a girl?
