Pregnancy 2nd Trimester
The second trimester of your pregnancy is a very exciting time that brings feelings of joy and bit of relief.
At this point, you can breathe a little easier in regard to miscarriage fears, and it is at this stage that your pregnancy starts to take shape, literally.
Starting to Show:
During the second trimester, you will notice you are starting to show, and your baby is growing at a pretty rapid pace. The baby is also becoming quite active, even though you may not feel movement right away. He or she is also forming a more solid skull, and the ribs are also starting to develop. The baby may also start putting his or her thumb in the mouth at this stage as well. The baby’s roof the mouth is just about finished forming by this time.
Early on in the second trimester, hormones are running rampant. This helps the ovaries or the prostate gland to develop in your baby. About the time the third week of the second trimester rolls around, your baby now has a fresh coating of skin, although it is essentially transparent. The eyes and ears have become more defined, hair on the head and the eyebrows form, and bone marrow starts to be produced.
By the time one month has passed into the second trimester, the baby now measures between four and five inches long and weighs about three ounces. The baby now becomes sensitive to light, and he or she can produce certain types of expressions, as well as make a fist. During this time, the fat layer, which will help to keep the baby warm and provide energy and protection, also starts to form.
During the weeks of the second trimester, you baby also learns to swallow. The brain is now fully functional with nerve function, and the ears have found their final resting place on the head. The baby can now hear your heartbeat, and your stomach noises. He or she can even react to sounds that are startling outside of the womb, which you may feel as the baby moving or fluttering.
Feeling baby move:
By week eighteen of pregnancy, it is quite possible that you may have felt some movement from your baby. If not yet, you soon will, especially at night. It is also by this point that your baby’s hearing is becoming better and he or she can hear conversations and voices. The baby’s muscles are now reflexive, and a coating of very fine hair known as languo is now covering the skin. He or she is also producing urine from the kidneys, which will be stored in the amniotic sac after it has been eliminated. Your baby begins to ingest sugar that is contained in the amniotic fluid during this time as well.
Boy or girl?
Somewhere between week eighteen and week twenty one, you will be able to find out your baby’s gender from an ultrasound test. By the end of week twenty one, the genitals are completely developed, and your baby weighs about one pound. Taste buds and the sense of touch are now also present.
By the end of the second trimester, your baby will start to practice breathing by moving amniotic fluid in and out of the lungs. The skin becomes thicker, the fat layer continues to develop, and finger prints are formed. The baby’s inner ear is now complete, and the baby knows if he or she is upside down or right side up in the womb. You may also notice your baby now has a sleep and wake cycle.
During this time you will also notice your baby has become much more active, and because the fingers and hands are now fully formed, he or she is having a great deal of fun exploring the environment that is your womb. By week twenty five, your baby now weighs about two pounds, and is starting to look like a baby with clear features such as eyes, ears, eyelashes, and eyebrows. By the end of the second trimester you will find the changes in both your body and your baby are much more pronounced.
The baby will have grown between three and four times its size since the end of the first trimester, and he or she is starting to prepare for life outside of your body.
