The Duchess of Cambridge was helped by Sunday night's full moon to deliver the royal baby, who was bound to take birth last weekend, it has been suggested.
The gravitational pull of moon is believed to have affected the amniotic fluid similar to the way it affects the water in the sea and rivers, the Daily Star reported.
Mervi Jokinen, of the Royal College of Midwives, revealed that midwives often chat up about how on a full moon they have a busy day.
She said that an old wives tale says that the full moon brings women into labour.
Jokinen explained that there was a study done nearly 20 years ago at a hospital near the River Thames - a tidal river - and it showed that indeed there were more births on the full moon.
She added that because the baby is surrounded by water, the time of the full moon and the high tide cause the water to break.
People also suggested that electrical storms and a drop in pressure could affect mums-to-be.
