Sleeping may be increasingly difficult now, as your body grows. Try propping yourself with pillows to help you find a more comfortable sleeping position. You might also try doing pelvic tilts before bed, and always urinate before laying down.

If you haven't started yet, try playing around with baby names! Look through your family history, read books, look at combinations for girls and boys. Remember to ensure that the initials don't spell something rude, and never give your kids the same initials!


At 20.5 cms or 8.1 inches total length, your baby is growing rapidly. S/he weighs about 7 ounces (198 grams). The bones are continuing the ossification process. The pads of the fingers and toes are formed and the fingerprints are developing as well.


When I asked my husband what a good tip for dads would be at week eighteen, he said "Don't tell your wife she's starting to look fat, because that's about when you really start poofing out." Take that for what it's worth, from the father of seven.

From trying to figure out if your baby if a girl or boy based on old wives tales, to pregnancy advice that just doesn't measure up (Like don't take a bath while pregnant...), there are a lot of things to figure out on your own.

The problem is that you never really know what's fact and what's fiction! What is the best old wives tale or other piece of not so true advice you've heard about pregnancy, childbirth or breastfeeding?
