The fetal period of development occurs during the third stage of prenatal development, which is the fetal stage.

The fetal period.
Pregnancy
Fetal Development period. Whereas the first 8-9 weeks is embryonic development or embryogenesis.
The stages of development in the gestational process, in order from beginning to end, are: fertilization, implantation, embryonic period, fetal period, and childbirth.
According to my college textbook, a critical period is an optimal period occurring in animals shortly after birth when certain events must take place to facilitate proper development.
The fetal mass increases at the greatest rate between weeks 9 to 14 of pregnancy. This period is known as the "growth spurt" stage of fetal development, where the baby's organs and body structures rapidly form and grow.
All stages of fetal development are important. The stages where the fetal development are most susceptible to developmental problems are the earliest ones. This is because the embryo starts out as one cell and then multiplies itself. This is the most crucial and vulnerable part of development because there are so few cells that any abnormality in the embryo's environment can lead to defects and even still birth.
The critical period was important because it was a time during development when certain skills or behaviors must be learned. If these skills are not acquired during this period, it can be much harder or even impossible to learn them later in life. This concept has been particularly studied in language acquisition and early childhood development.
Critical period refers to the time during a child's development when they are more easily taught things. Essentially, when a particular skill is most readily acquired.
