I had three daughters and didn't want to have more kids. Later, a friend of my husband introduced Dr. axial who said that 99% could have a son. We also wanted to have a daughter and a son, so we tried it. The result was really a son. I think it's amazing.Because the interval between my youngest daughter and son was 13 years. We want to say that we can have another brother for son. They can be close and grow up together. We went to see Dr. Xiao again and we gave birth to a son as we wish, Dr. Xiao is really great so amazing
