Through ultrasound investigation you may be able to find out the sex of your baby during your pregnancy, although not all hospitals will tell you. If you do decide to know, remember that this will deprive you of the wonderful surprise of finding out your baby’s sex at the birth.

I’m not in favour of trying to select a boy or a girl baby because I feel that nature does very well at maintaining a balance of about 103 boys to 100 girls and we shouldn’t interfere with that.

Couples wanting a third or fourth child, who already have all boys and who are longing for a girl – or the other way around – may feel differently!

There are many theories on the market about how to determine the sex of your baby. Some of them have more credibility than others but bear in mind that none have more than a slither of scientific validity.
