Pregnancy Week By Week Changes In Baby

In pregnancy week by week changes will happen with your baby.  In fact, many times babies will change, grow and develop day to day.  As a new mother or father, you may want to know what is happening with your child at any stage of pregnancy.  While there is some difference between each pregnancy, most pregnancies follow the same developmental stages.  You can know what changes your baby is having.  Take a look at the changes in baby over these pregnancy changes.

First Trimester Changes

First trimester changes during pregnancy will be the smallest in terms of mom, but they are significant for baby's development.  During the first weeks of pregnancy, the fertilized egg will implant into the uterus and will begin to develop a placenta.  From this point, cells multiple at an incredible pace as your baby begins to develop.  By the end of the first trimester, the baby will be about three inches long.  They weigh just about an ounce at this point.  In the first three months of pregnancy, your baby has ears and eyes moving into position as well as a liver that is making bile.  The kidneys are growing and secreting the baby's first urine. 

Second Trimester Changes

A look at the pregnancy week by week in the second trimester will allow you to see a lot of growth in your baby, including the fact that you will actually feel your child move towards the end of this trimester.  By the end of this trimester, your baby will weigh just less than two pounds.  He or she will be about 13 inches in length.  A closer look at pregnancy in the second trimester will reveal that the baby has developed fingers and toes as well as eyelashes and eyebrows.  With an ultrasound now, you are likely to see your baby's formation clearly.  Most babies begin to move in the fifth month too, so you may feel this happen surprisingly.  Plus, by the time this trimester is over, your child will have all of his organs in place and working including the lungs, heart and kidneys, though they can't sustain him fully just yet.

Third Trimester Changes

A closely look at pregnancy week by week in this trimester will show the child really becoming defined.  The baby is moving and growing now.  Your pregnancy weight gain is likely the highest here.  Weight gain during pregnancy will depend on your body, but as your child really grows now, he or she will move readily.  Your baby continues to grow and pushes at the abdomen.  The baby is able to open eyes now and may even suck his thumb.  Baby will also turn during the third trimester of pregnancy to ready itself for birth.  The baby is likely to be about 20 to 22 inches in length at the time of birth, on average, and weigh about seven to eight pounds on average. 

Pregnancy stages will differ from one person to another.  With a proper pregnancy diet and pregnancy exercise, you will give your baby all he needs to develop correctly.  Through ultrasounds and careful monitoring of your health, your doctor will work to know what' sharpening with baby in pregnancy.  What's more, your doctor is likely to give you all the information that you ask for, so ask questions about pregnancy at each visit so that you know what is happening with the development of baby.  With a look at pregnancy week by week, you will see an incredible development happening.  This amazing look is one that even doctors marvel at from time to time.  Your baby's development makes pregnancy enjoyable.
