Breathe, it won't be long now
Topics covered in your antenatal classes may include:
what happens during labour and birth
coping with labour and information about pain relief
exercises to keep you fit during pregnancy and help during labour
preparing for life with a new baby
caring for a newborn, including feeding
your own health in pregnancy and after the birth
relaxation
emotions surrounding pregnancy, birth and the early postnatal period
'refresher' classes for those who've already had a baby.

Most parents attend at least some antenatal classes. You're entitled to time off work to do so. Some employers will ask to see a note from your midwife or doctor recommending you go and confirming your attendance.
