First-time parents should consider taking a class to know what to expect and do during pregnancy, labor and delivery and even how to take care of a newborn baby. Knowing what to expect will keep you calm when your partner's contractions start - and you'll know how to support her through them. It doesn't have to be a lamaze class.
If you feel that you have no time or that it is an unnecessary expense, think again. The learning curve is steep and there's no such thing as cheating. Being with other soon-to-be parents is also fun and comforting.
If it's too late to join one, read books about pregnancy, labor and delivery or ask for advice from friends who are already parents. Your own parents can give you tips too but they might not be updated. For example, they may still believe in bigkis and crib bumpers.
