Invitations should be mailed about four weeks prior to the shower. This way, it is not so soon that people forget about it, but yet gives people enough time to make room in their calendar and to RSVP. Guests should RSVP no later than two weeks before the shower. People who are organized will open the card, check their schedule, and call right then, so it is important to have voice mail or an answering machine so they can respond immediately.

Watch out for cute and cuddly names that may seem very appropriate for a baby, but may not be so great later in life. Cozy or Bubby would be tough names to put at the top of a CEO staff memo!

Staying hydrated is also very important whether you are exercising while pregnant or not. Blurred vision is a common sign of dehydration. It means that your blood pressure is dropping rapidly which is sending your heart into overdrive. Make sure to keep drinking water to avoid this potentially dangerous situation.

Prenatal vitamins have been blamed for causing morning sickness because of the very high content of suppliments to which your body is unaccustomed. Don't stop taking them, but do take them later in the day or with food.
