Begins at fertilization, when the male sperm unites with the female ovum(egg);the fertillized single-celled egg is called a zygote.
Embryonic Stage of Development
Begins about two weeks after fertilization and lasts until the eighth week after conception.
Fetal Stage of Development
Begins after eight weeks,and the organism, now called a fetus,futher develops the organs and systems that exisited in rudimentary form in the embryonic stage.

By 6-12 months of age children become familliar with sentence structure and start babbling. By 11 months infants use symbolic gestures. At about 12 months infants use words to label objects. Between 18-24 months, toddlers combine 2-3 words into telegraphic speech.

2-5 years. Verbal and egocentric thinking develop. Can do mentally what once could only do physically. Conservation of shape, number, liquid are not yet possible.
Concrete Operational
6-11 years. Conservation of shape, number, liquid are now possible. Logic and reasoning develop, but are limited to appearance and what is concreatly observed.
Formal Operational
