My Boyfriend and I really want to have a baby boy first than a girl. Is there anything that we could do to help this or that I could do? I’m really curious about this. I tried to do research on this but found nothing. I always hear of couples doing curtain things to get the sex they wanted first but never explained. We aren’t trying to have any now but anything to keep in mind for the future would be great.
