My cousin has 4 boys. She would like to have another to try for a girl. She would be very happy with another boy but only wants to try if there is a chance she might have a girl.
Her doctor has told her once you have 4 of the same sex as a couple you are predisposed to keep having that sex and it is unlikely you will have one of the other sex.
It does make sense cos between us we know 2 families with 3 girls followed by 2 boys and one family with 3 boys followed by a girl. So it seems if you have 3 of the same sex there is still a good chance of having one of the other sex.
Then we know 2 families who had 4 boys and 4 girls and 1 ended up with 5 boys and the other ended up with 6 girls!! So it seems once you have 4 of the same sex it is unlikely you'll have 1 of the opposite sex.
The only exception to the rule is someone I know with 4 girls, followed by a boy but dd2 and dd3 are twins so ds was actually her 4th pregnancy rather than 5th.
Anyone like to disprove the doctor's theory?
