Your baby is about 5-6 inches now and typically weighs about 200 grams (or about 7 oz.)
Your baby is capable of moving, flipping and turning somersaults in your uterus. Did you know that your baby can make all of the following movements?:
If this is your first baby, you are likely to feel the first flutters of fetal movement, also called quickening, between week 16 and week 18. Mothers who have already been pregnant before (called multiparas or multips) notice these baby movements before first-time mothers (primiparas or primips.)
At first the sensation may feel like gas bubbles. But very soon, you will begin to realize that it is not gas pain but the baby kicking you! With time, you might even be able to discern different types of fetal movement (above.) There will be a big difference between a slow gradual movement of the baby stretching versus the rhythmic "beats" that can last for several minutes at a time. This could be your baby hiccuping!
It might be more comfortable for you at this stage to be wearing maternity clothing.
Continue prenatal vitamins and eating a healthy diet.
Have you started doing any pregnancy reading?
Be sure you have registered for childbirth classes. Some of the longer series of classes (such as the 12 week Bradley method) may actually be starting now.
