Swaying..

Jen
So I've heard people say if you want a "girl" do this but if you want to "boy"do that. Has anyone ever tried to sway while conceiving and did it work or fail? If it worked what did you do differently or do to get the gender you wanted? I was in publix the other day and the cashier asked if we had kids and I said no.. She said if you want a girl eat beef and if you want a boy eat fish .. I don't know how true it is to try to sway... Opinions..
