Hi, I know of only one family that has 4 dd's then went on to have a son. They didn't sway or do HT, infact, they were quite shocked that they got pregnant as they were using bc and weren't planning on having anymore. Needless to say they were thrilled to get their baby boy. Most of they families that I know that have all the same gender usually stop at three or four, most cannot aford to have more and most that are honest say they are afraid of having boy #4 or boy #5, girl #4 etc. I live in a neighborhood that has 4 boys and both women have said they just couldn't handle 5 boys so they stopped. I am not sure if I believe that swaying works for all, but it seems to work for some. GL.
