I think low is boy and high is girl.

I think it's hard to tell when your not really big all babys start off in the uterus witch is low so I think once you start getting bigger you can tell more

I don't think you can really tell gender from how you carry. With my daughter i carried low and now with my son I am also carrying low again so I think it has nothing to do with how you carry at all. Cute bump though. When do you find out the gender?
