It’s a rare baby that turns up on her due date, which means that most will be either early or late.
It’s still a mystery why some babies are late. In some cases, it may be that the due date has simply been wrong. Not that that’s much help to you and your partner as you sit there day after day wondering if this will be the day when it happens!
Provided the pregnancy has developed normally, there’s probably no need for doctors to intervene until you reach 42 weeks, although different units may have different policies. After this, there is a higher chance of problems at the birth.
It is sometimes necessary to start labour artificially. This is known as induction of labour. If this is necessary, your midwife will advise you.
