When do babies start to THINK?
Feel pain? At the 24th- 26th week the nervous system is developed enough to move and can therefore FEEL Pain!

Stages of Fetal Development
http://health.msn.com/pregnancy/slideshow.aspx?cp-documentid=100182842&imageindex=2
Month 1: Human development starts when a sperm fuses with an egg to create a zygote. A zygote is a single-cell that contains two copies of chromosomes—one copy from each parent. In the week following fertilization, the zygote undergoes rapid cell division and becomes a mass of cells known as a blastocyst. After more cell division, the blastocyst splits in half.
One half of the blastocyst will become the placenta and the other half will become the fetus. But just 12 days after fertilization, the cells destined to become the fetus turn into something else first: the embryo.
By the month’s end, this embryo is about the size of a grain of rice, and it looks more tadpole than human, donning a tail in lieu of legs. But already, its surface features and major organs—the heart, lungs, liver and kidneys—are starting to take shape.
Attention expectant moms: Exposure to high heat during early pregnancy may be risky business. Researchers at Boston University found that if expectant moms climbed into a hot tub or sauna or suffered a high fever during their first trimester of pregnancy, their baby faced an increased risk of developing neural tube defects (NTDs). Lounging in a hot tub is riskier than exposure to a sauna or fever, according to the study, which was published in the medical journal JAMA. The researchers also found that cuddling up with an electric blanket during the first few months of pregnancy posed no risk for NTDs.
Month 2: This month, the embryo’s development shifts into high gear. Its tongue, teeth and eyelids start to form. Its limbs grow longer and stronger, and its palate is nearly complete. Also in this time period, the embryo’s gastrointestinal tract separates from its urogenital organs and its heart begins beating—twice as fast as yours, in fact.
The essential organs all are under construction and major body parts are in place (legs, arms, head and torso). As the eighth week of pregnancy draws to a close, one more major development unfolds. The embryo gets a final name change, and it is now called a “fetus” until birth.
Attention expectant moms: The latest science news warns that you should think twice before taking pain pills. A study published September 2006 in the journal Birth Defects Research Part B found that pregnant moms who took non-steroidal anti-inflammatory drugs (NSAIDs) during their first trimester put their unborn child at risk for developing congenital birth defects—especially heart defects. Popular brands of NSAIDs include Motrin, Advil, Aleve and Celebrex, and the study’s authors are calling for more research to confirm their findings.
Month 3: This is the month of the heartbeat. Using a special tool called a Doppler monitor, doctors can detect the tiny thump-thumps of a 10-week-old fetus.
This is also a time of rapid growth inside the womb. By month’s end, the fetus will weight roughly 1 ounce, and it will double in length, uncurling from a tight C-position until it’s about 3 inches long. The tail will disappear and its eyelids, earlobes, limbs and digits will continue to form.
Other developmental milestones for this period include thumb-sucking, head-nodding and balling tiny fingers into fists. And though the fetus’s reproductive organs now are under construction, it’s still a bit early for the doctor’s gender declaration. That news (should you want it) usually arrives early in pregnancy’s second trimester.
Attention expectant moms: As many as seven out of 10 women suffer morning sickness during the first trimester, according to the Mayo Clinic. But new research conducted by two scientists from the University of Liverpool suggests that poor diet—and not raging hormones—may be the root of your upset stomachs. After reviewing nausea and diet data from pregnant women around the world, the scientists found that women who feasted regularly on sugars, alcohol, oils and meats were more likely to suffer symptoms of “morning sickness” relative to their cereal-munching cohorts. The theory here is that expectant mothers are hardwired to purge their body of hormone-heavy foods (like meats and dairy) in order to protect their vulnerable and growing fetus.
From the 16th to 20th week, the baby undergoes another rapid growth spurt. He begins to develop fat under a thin skin. The heart pumps a staggering 25 quarts of blood every day. Meconium, a baby’s waste product, accumulates in the bowel. The fetus regularly hiccups and spends the same amount of time awake and asleep as a typical newborn.
I wonder if the baby cries and caries on in the womb as it does when it comes out?
