Baby

Your baby continues to grow steadily, gaining half an inch in the last week! Now, about the size of a kiwi fruit, your baby has reached an important developmental milestone. Week 10 is the beginning of the fetal period, in which your baby's organs rapidly mature.

This week, his kidneys, liver, heart and intestines are forming tissue. Toenails and hair begin to grow and add detail to your baby's body. Your baby's limbs are now able to flex. His wrists are bent and his hands meet over his heart and his legs may be long enough for his feet to meet in front of his body as well. He will even start swallowing and kicking this week, but don't expect to feel anything yet, those movements are still too little!

Your baby is also less susceptible to certain birth defects and congenital malformations by the time he has reached the fetal period. It is important to remember however, that certain toxins, like second-hand smoke, are never good for your developing baby and should always be avoided!

Mom

By week 10 your uterus is the size of a grapefruit. To put that into perspective, just a little over two months ago, before you were pregnant, it was the size of small pear. You may notice your midsection thickening a little by this week. And though it may not be time for maternity clothes, don't be concerned if your normal wardrobe is beginning to feel a little snug!

Not ready for maternity clothes? Look for clothing with elastic waistbands. You may already own some forgiving pants and skirts, but shopping for clothing with elastic in the waist might be just what you need to accommodate your expanding midline.

Are you up and moving? As you may be experiencing morning sickness, midday sickness, nighttime sickness or fatigue, it might be easy to forget that depending on your level of fitness, you can most likely participate in a wide range of physical activities during your pregnancy. Swimming is an excellent option. No access to a pool? Don't worry about it; walking is a great option too. Exercise can help you build muscle tone, strength and endurance, which can help you carry the weight you are about to gain and help prepare you for labor.

Not sure about exercise? If you have any doubts or questions about exercising during your pregnancy, be sure to check with your physician. Your doctor may even be able to help you decide on the type and level of exercise that is right for you.
