This simple test using your baby’s 12-week scan is believed to be 92 per cent accurate in predicting your baby’s sex.
Called the “skull theory”, the idea is that you can tell your baby’s sex from the shape of their skull in the picture.
To test it out, you need to have:
- your 12-week scan picture
- a magnifying glass
- info on skull shape and size
According to Netmums, boys do tend to have bigger heads and girls have rounder heads in their scan pictures.
