the number of childhood death experiences a decrease
I think that you mean that children die less often. So you would replace that sentence with " infant mortality rates have decreased " or" infant mortality rates are decreasing"

that brings this number get lower is related
can be replaced with " leading to this decrease relates "

a lot of the words in your essay do not make sense so I would advise you to revise it , understanding it as though you were the reader.

Try editing it and adding my hashtag so that I can review it and see if it fits in the ears of a reader.

@dils
I think you should try an oppening that invites the reader to engage to your story, try something like "with the advance of technology today, doctors have reach the solutions to sirious problems"

good luck!
