1. You aren't actually going to break a sweat. Even a cardio class is gentle. Any burn you may feel while doing squats is a bonus. The bigger your belly gets, the more okay you will be with this. You will also realize that the biggest draw of the class is not actually the workout itself but the chance to gab with other expecting mothers - it's a great opportunity to discuss whatever it is you're obsessing over this week without your husband having to hear about it for the umpteenth time.
2. You will not have time to work out during subsequent pregnancies. Of the dozen or so gals I've met in the class, all but two are first time mothers. I'm just hoping that chasing after baby number 1 keeps you in good enough shape for the arrival of numbers 2 on.
3. Mommy wars don't begin until after you've had a child. Almost every woman in the class is still trying to gather information and figure things out - most gals don't know what they're going to do yet! And if they do have an idea, they refrain from criticizing anyone else's choices, perhaps because without firsthand experience they can't be sure about anything yet.
4. There is someone out there who can't wait to get the baby item that you consider the most ridiculous and unnecessary. You will not open your mouth, both because that would be rude and because you would hate to say something and then find out she was right (see 3). You may still make a comment to your husband as soon as you get home, though.
5. Never comment on how far along someone is based on how they look. You will think they are farther than they are and feel like a jerk. Always ask when they are due first; if they look super big, you may ask if it's their second baby.
6. Respect for husbands varies. Some women consider their husbands complete wimps. Don't allow their low expectations to affect your own attitude and never join in mocking your man.
Okay, I've shared my observations. So what are some things you've learned in prenatal classes?
