Mommy Blog 11/15
Today was the third day having a baby. Each day seems to be getting harder and harder having to carry to the baby around. Being at my locker and having the baby in the other arm just makes it more difficult to do anything else. Having to carry the baby around all day starts to make my arm hurt after a while. Doing this project makes me realize how much responsibilty there is when you have a baby.

Today was the second day having to carry a baby around. Having the responsible of carrying the baby has showed me to respect thing better and is making me more responsible. Before i could carry stuff in both hands now i have to go through the trouble of grabbing and doing things with only one hand because the baby is being held in the other hand. Carrying around the baby has been really tiring and starts to get heavy after holding it so long. Having to carry the baby made me realize how much work it is to have a child.

Mommy Blog, 11/11
Today was my first day being a mother and having to carry around a real baby. I am really excited to have a baby girl but there are also some big responsiblities tat come with having this baby. It was really hard to have to carry the baby around all day. The baby would fell like it was getting heavier and it would make it harder to carry. Having to carry the baby meant only one arm was free to use, so when you had to carry something it was harder with only one hand. you could never really put the baby down so it was hard to do anything else with only one arm to use. Carrying this baby around made me notice all of the problems that come with having a baby.

Day 5
Life Card- Some of the mothers blood work has come back suspicious.. what might be wrong?
Second trimester prenatal screening may include several blood tests, called multiple markers. These markers provide information about a woman's risk of having a baby with certain genetic conditions or birth defects. Screening is usually performed by taking a sample of the mother's blood between the 15th and 20th weeks of pregnancy (16th to 18th is ideal). The multiple markers include:
- An alpha-fetoprotein (AFP) blood test checks the level of AFP in a pregnant woman's blood. AFP is a substance made in the liver of an unborn baby. The amount of AFP in the blood of a pregnant woman can help see whether the baby may have such problems as spina bifida and anencephaly.
- Chorionic villus sampling (CVS) is a prenatal test that involves taking a sample of some of the placental tissue. This tissue contains the same genetic material as the fetus and can be tested for chromosomal abnormalities and some other genetic problems.
- An amniocentesis is a procedure used to obtain a small sample of the amniotic fluid that surrounds the fetus to diagnose chromosomal disorders and open neural tube defects (ONTDs) such as spina bifida. There is a small risk of miscarriage associated with amniocentesis which must be balanced with the risk of an abnormality and the patient’s desires.
Week 17: Your baby, now about in its 15th week of development, measures about 4.4 to 4.8 inches from crown to rump and has doubled in weight in the last two weeks to about 3.5 ounces. Fat begins to form, helping your baby's heat production and metabolism. The lungs are beginning to exhale amniotic fluid, and the circulatory and urinary systems are working. Hair on head, eyebrows and eyelashes is filling in.
Week 18: Your baby measures 5 to 5.6 inches from crown to rump and weighs about 5.25 ounces. The rapid growth spurt is tapering off, but reflexes are kicking in. It can yawn, stretch and make facial expressions, even frown. Taste buds are beginning to develop and can distinguish sweet from bitter tastes. The baby will suck if its lips are stroked and it can swallow, and even get the hiccups. The retinas have become sensitive to light, so if a bright light is shined on your abdomen, baby will probably move to shield its eyes.
Week 19: Your baby measures about 5.2 to 6 inches from crown to rump and weighs about 7 ounces. Skin is developing and transparent, appearing red because blood vessels are visible through it. Creamy white protective coating, called vernix, begins to develop.
Week 20: The fetus measures about 5.6 to 6.4 inches from crown to rump and weighs about 9 ounces. Your baby can hear sounds by now -- your voice, heart and your stomach growling, as well as sounds outside your body. It will cover its ears with its hands if a loud sound is made near you, and it may even become startled and "jump." The baby is moving often, too -- twisting, turning, wiggling, punching and kicking.
Week 21: Your baby measures about 7.2 inches from crown to rump and weighs about 10.5 ounces. The fetus is steadily gaining fat to keep warm. Growth rate is slowing down but organ systems, like digestion, are continuing to mature. A waxy film, called the vernix caseosa, is being produced by your baby's oil glands and covers the skin to keep it supple in the amniotic fluid. Buds for permanent teeth are beginning to form.
Week 22: Your baby measures about 7.6 inches and weighs about 12.3 ounces. The muscles are getting stronger every week now, and the eyelids and eyebrows are developed. Your baby's acrobatics are pretty constant, and since he responds to sound, rhythm and melody, you can try singing and talking to him. After he's born, the same sounds will soothe him.
Week 23: Your baby is about 8 inches from crown to rump and weighs almost 1 pound. The body is becoming proportioned more like a newborn, but skin is still wrinkled because your baby still has more weight to gain. Lanugo hair on the body sometimes turns darker.

Day 4
New Life Card- Husband got a new job at the nuclear power plant. What are the affects in the Mom and Baby? The radiation and the radioactive waves can be exposed to the husband at the plant and then bring them home and expose them to the rest of the family. The baby when exposed to the radiation, can cause harmful health effects.
Time Line
Week 8: Your baby will be about 8-11 mm CR by the end of the week. The baby's hind brain is clearly visible. This week the baby's gonads will become either testes or ovaries. Movemwnt begins to occur. Bones and joints this week have many things going on. Elbows appear and the process of ossification (hardening of the bones) begins.
Week 9: We have elbows! Your baby is now approximately 13-17 mm crown to rump length, or about 0.51 - 0.66 inches. S/he also weighs in at 1 gram! Toe rays are present as the toes begin to form. Gonads have become testes (for boys) or ovaries (for girls). Baby will move away if touched through the uterine wall, and can spontaneously move as well. Ossification (hardening) of the bones may begin.
Week 10: The baby now enters its fetal period. The average size is approximately 27-35 mm crown to rump length (CRL), or 1.06-1.38 inches. S/he weighs in at 4 grams, or 4 paper clips. Tiny toes have formed. The eyes are largely open, but the eyelids are beginning to fuse, and will stay that way until
25-27 weeks. External genitalia is beginning to differentiate. External ears are formed, as is the upper lip.
Week 11: If you have seen pictures of baby at this stage you will notice that the head is about 1/2 of the body size. This will change as the baby grows. The iris will begin to develop this week and finger nails appear! Your baby weighs about 7 grams.
Week 12: While your baby's brain is not the same size it will be at birth, it does have the same structure. Bile is being secreted by this time. S/he weighs about 14 grams and is approximately 3.54 inches in total length.
Your baby has its reflexes and also practice movements in the digestive tract.
Week 13: There are a lot of things going on this week! All twenty teeth have formed and are waiting. Your baby approximately weighs in at 1 ounce (28.3 grams). Consider that the placenta weighs about an ounce now as well.
Week 14: The baby is now about 12.5 cms or 4.92 inches. Your baby is now producing urine and actually urinating into the amniotic fluid. It also can practice "breathing" the amniotic fluid in and out of its lungs.
Week 15: Your baby may have developed the habit of sucking his or her thumb! The skin is very thin and you can see the blood vessels clearly underneath.Your baby is about 70 grams. The scalp hair pattern is developing. And the heart is pumping about 25 quarts of blood a day. This will increase to about 300 at term.
Week 16: Your baby's nails are well formed, and some babies are even in need of having their nails trimmed at birth. The ears have also moved from the neck to the head. Your baby is emptying his or her bladder every 40-45 minutes. The limb movements are becoming more coordinated. Your baby is about 3 ounces (85 grams) and 6.3 inches (16 cms).

Cell Differentation
What is the differentiation of cells?
Cell differentiation is a process in which a generic cell develops into a specific type of cell in response to specific triggers from the body or the cell itself. This is the process which allows a single celled zygote to develop into a multicellular adult organism which can contain hundreds of different types of cells. In addition to being critical to embryonic development, cell differentiation also plays a role in the function of many organisms, especially complex mammals, throughout their lives.
The steps involved in differentiation:
Ectoderm- The ectoderm forms the central nervous system, the lens of the eye, cranial and sensory, the ganglia and nerves, pigment cells, head connective tissues, the epidermis, hair, and mammary glands.

The germ layers and the systems formed from them:
Endoderm- The endoderm forms the epithelial lining of the whole of the digestive tube except part of the mouth and pharynx and the terminal part of the rectum.
Mesoderm- The mesoderm forms the skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood, and the spleen.Ectoderm- The ectoderm forms the central nervous system, the lens of the eye, cranial and sensory, the ganglia and nerves, pigment cells, head connective tissues, the epidermis, hair, and mammary glands.
