Final answer:
Children develop at different rates, but typically around 12 months they may start walking, use a few words, and follow simple commands. By 2 years, they walk independently, use a sippy cup, and understand more complex commands. By 4 years, they form sentences and have improved motor skills, and by 5 years, they are conversing and recognizing written language.
Step-by-step explanation:
Developmental Milestones for Children
Children typically reach certain developmental milestones as they grow. At around 6 months, infants begin using two-syllable sounds like "mama" or "dada" and can sit up. By 12 months, they are often able to stand with assistance, may begin walking, follow simple commands, and use simple words such as "ball". Additionally, they start to exhibit separation anxiety and show understanding of object permanence.
By 2 years of age, toddlers can walk independently, including sideways and backward. They run, though not perfectly, and can navigate stairs with assistance. Their vocabulary increases to around 50 words, and they can obey simple verbal commands. Two-year-olds have also typically mastered using a sippy cup and can feed themselves with a spoon. They might show signs of temper tantrums as a sign of growing independence.
Reaching the age of 4, most children can use sentences, run, climb stairs with ease, and scribble with crayon. They continue to broaden their language skills, consisting of many words and beginning to use proper past tense of verbs. Additionally, children at this age are usually toilet trained.
By age 5, children can converse, recognize letters and words, and have more refined motor skills, such as being able to tie their shoelaces or ride a bicycle.
