The development of babies in the mothers’ womb can differ very greatly but there may be one thing in common – all expectant parents find that process quite fascinating. So here, in short are the kinds of changes that a baby typically goes through in the 9 months that it spends in its mother’s womb.
The all important process of implantation takes place about a week after conception, when the embryo attaches to the walls of the uterus and then the formation of the placenta (to nourish and sustain the baby) and the umbilical cord (that attaches the baby to the mother) begin to form. The basis of the spine forms and at around 25 days the heart starts to beat.
This is a crucial time of development for the baby for all the major organs such as the brain, stomach, lungs liver, the rudiments of the bone structure etc begin to develop. At this critical time of development the baby is most vulnerable to factors that could result in miscarriage or birth defects. At the end of the second month the baby is called a fetus and the first indications of what sex the baby will be start to emerge.
The bones start to develop now and there is some movement from the fetus which mother will not be able to feel yet. The head is about 50% of the baby’s body at this time.
The baby now starts to do a lot of what a new born will do – sleeping, waking, moving, kicking, swallowing, and passing urine. Fingernails appear now, the teeth buds are formed, the body is covered by the fine pelt of hair called lanugo and baby is about half a foot in length. Baby can probably hear by now, and this may be the time that the parents start to speak with their baby.
As some of the discomforts of early pregnancy fade about now, mother may feel more energetic and upbeat and for the baby it is a time of rapid growth as the baby develops bones, muscles, and starts to acquire some fat stores as well. The baby is nearly 10 inches now and the baby bump is very clear to see.
Most excitingly, the expectant mother is now feeling her baby move though some women (particularly second time mothers) may have experienced this earlier on in the pregnancy. At this stage the baby looks much like a human being and may be 11 to 14 inches long.
The baby is bigger now, and it’s getting cramped in there, so that there may be less room for baby to move and kick around in. The expectant mother may find that baby startles at sudden noises and may feel this very clearly.
Baby puts on a lot of weight in these last couple of months and each day is becoming stronger and more likely to survive if he or she were born early. Baby is now nearly 4 pounds and measures about 16 inches. The mother can probably see quite easily now, the head sticking out here or heel pressing there through the stomach wall.
The baby is just about ready to enter the world now, and is big and strong enough to survive as an individual. These 9 months were probably the easy part; the real work begins now, so Good Luck.
