Hello.
"By 14 months most children have said their first word (bye-bye, mama,
baba, blankie). Between the ages of approximately 12 and 24 months,
the toddler delights his parents by labeling and describing his
environment (nana, juice, doggie, up, more, gone, push), revealing the
growing vocabulary he has been working hard to acquire. This
single-word vocabulary gives rise to word combinations by 18 to 24
months (more juice, doggie gone) and phrases (me all finish, dat my
car) a little later. By age three, with seemingly little conscious
effort or instruction, most children will be beginning to speak in
multi-word phrases or even complete sentences...
This is how speech and language skills develop for ninety percent of
young children."

"By six months of age, an infant usually babbles or produces
repetitive syllables such as "ba, ba, ba" or "da, da, da." Babbling
soon turns into a type of nonsense speech (jargon) that often has the
tone and cadence of human speech but does not contain real words. By
the end of their first year, most children have mastered the ability
to say a few simple words...
By eighteen months of age, most children can say eight to ten words.
By age two, most are putting words together in crude sentences such as
"more milk." During this period, children rapidly learn that words
symbolize or represent objects, actions, and thoughts. At this age
they also engage in representational or pretend play. At ages three,
four, and five, a child's vocabulary rapidly increases, and he or she
begins to master the rules of language."
