why does a baby cry when she/he is born?

New born baby cry to expand its lungs, it is also a respond to the ordeal that its through.As you can notice, doctors deliberately make them cry to encourage them to take their first breath of air.If they don't cry, the doctor or nurse do something to make them cry and take the amniotic fluid out. It is also a way to helps their blood circulates better, oxygenating it,you can see their pale color,once they start crying it will turn into red.The oxygen they are taking into crying oxygenates their blood.After giving birth, they will cut the placenta, which is the source of their breathing. Now its gone, they need to breath of their own.

Because it is a natural response. The baby has to cry because of the onslaught of air into his lungs because of atmospheric pressure. As the air rushes into his lungs he cries as a natural, instinctive response. When a baby does not cry as he comes into the world then it is a cause for more worries than one who cries loudly. That's why the doctor slaps the baby's rump to make him cry. Merry Christmas. .

Intially to expand its lungs.Doctors deliberately make them cry to encourage them to take their first breath of air. Everything is up to them from that time till the they take their last.

Nice idea... you can use it very well as a figure of speech...it's really bright! The child, especially the new-born are very sensible to change. Whenever their phisical state is changed without their will (if they have one) they cry. They don't know what happens...they only stop crying when they understand or when they forget...or when they grow up The big majority of people is resistent to change...that's why the ones who do manage to perform the change become leaders...and this is the reason they are so few! ~ ...in my opinion... feel free to express yours ~

I think it is a natural response to being thrust from a warm, dark, quiet, safe and comfortable place into the bright lights, noise and action of a delivery room. When a baby does not cry it gets slapped until it does, just to show that he or she has normal natural responses. It could also be a lesson that life starts with a cry of anguish and from then on things will never be as easy or as comfortable as they were inside the womb.

In Genesis when God created Adam....Adam wasn't anything until God breathed his soul into him. I think when a baby is born, God breathes its soul into him/her ..... that's when the baby takes it's first breath as it cries out.

No, I think it is basically the sharp change of environment from the regulated comfort of the woumb to the harsh world of chills or extreme heat! Crying is also a response to the first use of the lungs-remember the child did not breathe while in the woumb, now it has to by using his/her lungs and a heaving cry is nature's way of making a child draw the first air into the lungs! A good post here-thanks sutan..

I think it hurts them to have the umblical cord snipped!!!!!

Not all babies cry instantly when they were born. Some have to get a little spank from the doctor for them to cry. I think crying would help them breathe. I think it is also a sign that the baby is normal and a signal to the mother that her baby was born. It is really wonderful for a mother to hear her baby's first cry based on my experience.

a child is born with his five senses . expression of these senses is emotion . these senses comes into action when they are born .what it e wich a child doesnot likes he cry for it .
