Women carry boys higher and girls lower, or do they?

Being a prenatal and postpartum massage therapist for the past 12 years and a Infant Massage Instructor for the last 7, I have seen a lot of pregnant women.  I have always heard the old wives tale that boys are usually carried higher and girls are lower. I have also heard the exact opposite. So, I am conducting a survey of pregnant women in different stages of pregnancy, to see if the old wives tale is true.
I am also interested if the general public can tell what they are carrying. I’m not sure how long this survey will last or how many women will be included, I just got this idea.  However at the end of each month, I will post what each mama is carrying.
I am always open to discussion and other thoughts!

BeWell!
