The story of our lives begins with a small unit of blood in the embryo that overwhelms the parents as soon as they get informed about it. Well, that's a part of life.
Apart from the fact that a new born life brings hope and happiness let us now change our focal point towards the new infant that is being developing inside the mother's core.
The unborn developed baby grows and along with the process of growing, it also starts adapting the environment around him. He gets used to an environment that is far distant from the uncanny nature of the world, the insecurities and the worries. He/she somehow becomes very used to the environment totally safe and sound by care and love.
Day passes by and gradually a day comes when he finally feels compelled to leave that safe zone and get exposed to the harsh realities of the world. Post the commencement of a new life, the child starts facing challenges and troubles and the world outside seems to be very unacceptable towards him. A child gets vaccinated, utterly pampered just to survive in the world. The stage of infancy doesn't allow our senses to work well as that is why, we usually don't focus or never notice the fact that the struggle to live begins right after birth. For the world, it appears to be just cry or fretfulness but the child knows how difficult things are being for him and what all he is doing to survive.
It's more like when we shift to a totally different place out of our comfort zone and get exposed to that place forcibly. All we do is we observe with our eyes and try to figure out the environment, the people and other necessary things.
