First trimester baby development is where new life really starts.
Let’s first clarify a few things…
Three pregnancy trimester periods make up your pregnancy period.
These are…
-
First
Trimester Pregnancy: From conception to 12 weeks,
-
Second
Trimester Pregnancy: 13 weeks to 27 weeks,
-
Third
Trimester Pregnancy: 28 weeks to delivery
The growth of a baby in her mother’s womb is an extraordinary event,
when a series of morphological changes gives a small fetus, a definite
shape and a lovely figure. While the baby is growing in your womb,
Nature has provided her an ingenious way, by using which she can sustain
herself and grow into a healthy body.
First Trimester Baby Development: Conception to 12
weeks
Baby
development starts right from conception, when a highly motile sperm
impregnates a highly fertile egg. At this initial stage, the sperm
penetrates the ovum and fertilizes it to create a small node like cell
mass called zygote. This little zygote takes three to four days to reach
the warm and cozy environs of the uterus. All these significant
developments will be carried out within the first two weeks and this
process lays the foundation for the creation of a beautiful baby.
Throughout
the fourth week, there are a series of developments within the uterus.
The embryo may float in the uterus for more than 48 hours, before
implanting onto the walls of uterus. Once there is a confirmed
connection between the embryo and the uterine wall, a highly
sophisticated tool called placenta, starts developing to connect embryo
and the uterus. This is often called the lifeline for the undeveloped
baby, as it is the root through which life support is provided to the
unborn baby.
By about the
sixth week of pregnancy, the embryo reaches about 1/5th of an inch and a
primitive heart develops and starts beating. Several organs like head,
mouth, liver and embryo will also start developing at this time.
Well into
the eighth and tenth week of pregnancy the embryo becomes quite larger
in size (1 inch) and several facial and limb features become visible
under an imaging machine. At this stage the baby can perform several
activities all related to the nervous system.
Stated
differently, first trimester baby development surely is the basis of new
life.
Second
Pregnancy Trimester: 13 weeks to 27 weeks
The second
pregnancy trimester is a phase of consolidation, when all the external
and internal organs start stabilizing into a well organized and cohesive
unit. Throughout the weeks fourteen and twenty-two, the fetus develops
into a strong and virile body and performs several actions and functions
like beating hands, moving limbs and clenching the fist.
It is also
easy to notice the development of other critical organs like finger
nails, toe nails ands eye lids. The tiny tot can move and shift her
body, limbs and hands with a considerable ease.
Third
Pregnancy Trimester: 28 weeks to delivery
The third
trimester is a critical phase when the baby development involves growth
and development of all organs - both internal as well as external. The
baby can even cry. At this critical stage your baby develops the ability
to sustain the rigorous environmental conditions of outside world. This
pregnancy trimester also marks the end of the nine months growth period.
At the end of this period your baby is ready to face the outside world
and lead a happy life with her mother and father!
