Antenatal classes can help you to prepare for your baby’s birth and learn to look after and feed your baby. They can help you to stay healthy during pregnancy and give you confidence and information. You can learn about the different arrangements for labor and birth, and the choices available to you. This can help you to make your own birth plan. You’ll be able to discuss your plans and worries with professionals.

You might be able to attend introductory classes on baby care early in pregnancy, but most antenatal classes start around 8-10 weeks before your baby is due, when you are around 30-32 weeks pregnant. If you’re expecting twins, start your classes when you’re around 24 weeks pregnant because your babies are more likely to be born early.

• Health in pregnancy ,including a healthy diet
