The toddler years are a time of great cognitive, emotional and social development. The word is derived from `` to toddle '', which means to walk unsteadily, like a child of this age.

There is reasonable consensus about what these areas may include : Physical : growth or an increase in size. Gross motor : the control of large muscles which enable walking, running, jumping and climbing. Fine motor : the ability to control small muscles ; enabling the toddler to feed themselves, draw and manipulate objects. Vision : the ability to see near and far and interpret what is seen. Hearing and speech : the ability to hear and receive information and listen ( interpret ), and the ability to understand and learn language and use it to communicate effectively. Social : the ability to interact with the world through playing with others, taking turns and fantasy play. Although it is useful to chart defined periods of development, it is also necessary to recognize that development exists on a continuum, with considerable individual differences between children. There is a wide range of what may be considered ' normal ' development. One year old 12 - month - old toddler sitting in a bucket At one year of age, the typical toddler will be able to display the following skills : Physical and motor skills A typical one - year - old toddler 's body proportions Triple the birth weight Grow to a height of 50 % over birth length Have a head circumference equal to that of the chest Have one to eight teeth Pull to stand Walk with help or alone Sit down without help Bang two blocks together Turn through the pages of a book by flipping many pages at a time Have a pincer grasp Sleep 8 -- 10 hours a night and take one to two naps Sensory and cognitive development Learning to eat independently Follows a fast moving object Can respond to sounds Responds to his or her name Understands several words Can say mama, papa, and at least one or two other words Understands simple commands Tries to imitate animal sounds Connects names with objects Understands that objects continue to exist, even when they are not seen ( object permanence ) Points to objects with index finger Waves bye bye May develop attachment to a toy or object Experiences separation anxiety and may cling to parents May make brief journeys away from parents to explore in familiar settings Two years old Weight : about 11 -- 13 kg Height : about 80 -- 82 cm Teeth : 12 temporary Two and half years old Learning to ride a toy car Teeth : full set of 20 temporary Decreased need for naps Becoming inquisitive Motor development Running and falling 14 months Using a spoon Walks well alone with wide based gait Creeps upstairs Builds with blocks Drinks from a cup, uses spoon Enjoys throwing objects and picking them up 18 months Walks sideways and backwards, runs well, falls easily Climbs stairs or up on furniture Scribbles vigorously, attempting a straight line Drinks well from a cup, still spills with a spoon Two years Gross motor skills are quite well refined, can walk up and down stairs on both feet with one step at a time while holding on to a rail Builds tower of five cubes Control of spoon well - developed Toilet trained during day time Vocalization and socialization 15 months Can use 10 - 15 words Says `` no '' ( see holophrasis ) Indicates when diaper is wet 18 months Uses phrases composed of adjectives and nouns Begins to have temper tantrums Very ritualistic, has favorite toy or blanket Thumb sucking may be at peak Two years Vocabulary of about 350 words Obeys simple commands Helps undress self and put on simple clothes Shows sign of increased autonomy and individuality Does not share possessions -- everything `` mine '' as in the `` Toddler 's Creed '' : `` If I want it, it 's mine.

If it 's mine it will never belong to anyone else, no matter what. If we are building something together, all the pieces are mine. If it looks like mine, it 's mine. '' -- Burton L.

( December 2010 ) Child plays alongside other children but not with them Mostly free and spontaneous, no rules or regulations Attention span very short and change of toys occurs at frequent intervals Imitation and make - believe play begins by end of the second year Games : throwing and retrieving objects Suggested toys : Play furniture, dishes, cooking utensils, play telephone, puzzles with large pieces, pedal propelled toys, rocking horse, clay crayons, finger paints, pounding toys, blocks, push - pull toys, balls Squatting Main article : Squatting position Young child playing at ease in a squatting position Young children squat instinctively as a continuous movement from standing up whenever they want to lower themselves to ground level. One - and two - year - olds can commonly be seen playing in a stable squatting position, with feet wide apart and bottom not quite touching the floor, although at first they need to hold on to something to stand up again. Language Talking is the next milestone of which parents are typically aware. A toddler 's first word most often occurs around 12 months, but again this is only an average. The child will then continue to steadily add to his or her vocabulary until around the age of 18 months when language increases rapidly. He or she may learn as many as 7 -- 9 new words a day. Around this time, toddlers generally know about 50 words. At 21 months is when toddlers begin to incorporate two word phrases into their vocabulary, such as `` I go '', `` mama give '', and `` baby play ''. Before going to sleep they often engage in a monologue called crib talk in which they practice conversational skills. At this age, children are becoming very proficient at conveying their wants and needs to their parents in a verbal fashion. Emotions and self - image 23 - month - old crying girl There are several other important milestones that are achieved in this time period that parents tend not to emphasize as much as walking and talking. Gaining the ability to point at whatever it is the child wants you to see shows huge psychological gains in a toddler. This generally happens before a child 's first birthday. This age is sometimes referred to as `` the terrible twos '', because of the temper tantrums for which they are famous. This stage can begin as early as nine months old depending on the child and environment. Toddlers tend to have temper tantrums because they have such strong emotions but do not know how to express themselves the way that older children and adults do. They also throw tantrums to let others know that they are free and can do what they want. The toddler is discovering that they are a separate being from their parent and are testing their boundaries in learning the way the world around them works. Although the toddler is in their exploratory phase, it is also important to understand that the methods used by the parents for communicating with the toddler can either set off a tantrum or calm the situation. Research has shown that parents with histories of maltreatment, violence exposure, and related psychopathology may have particular difficulty in responding sensitively and in a developmentally appropriate manner to their toddlers ' tantrums and thus may benefit from parent - child mental health consultation. This time between the ages of two and five when they are reaching for independence repeats itself during adolescence. Self - awareness is another milestone that helps parents understand how a toddler is reacting. Around 18 months of age, a child will begin to recognize himself or herself as a separate physical being with his / her own thoughts and actions. A parent can test if this milestone has been reached by noticing if the toddler recognizes that their reflection in a mirror is in fact themselves. One way to test this is the rouge test : putting lipstick on the child 's face and showing them their own reflection. Upon seeing the out - of - the - ordinary mark, if the child reaches to his or her own face, the child has achieved this important milestone. Along with self recognition comes feelings of embarrassment and pride that the child had not previously experienced. Overview The toddler developmental timeline shows what an average toddler can do at what age. Times vary greatly from child to child. It is common for some toddlers to master certain skills such as walking well before other skills, like talking. Even close siblings can vary greatly in the time taken to achieve each key milestone.
