The process of initiating a life that will grow inside you will always be a special one. Both the parents are equally responsible for the proper parenting and upbringing of the child. In the initial weeks of pregnancy, the mother’s body is getting used to the changes that come by bearing a child. The first change you ask? The mother starts throwing up and rushes to the bathroom early morning. When she is fully accustomed to this, she still has to cope-up with the various emotional changes that come with the responsibility of bearing a child. Around this time, the 21 weeks pregnant fetal development is in a blastocyst from which then changes into an embryo, and gradually into a fetus, finally taking the form of a baby later.
