How do we communicate with each other? Through language both verbal and non verbal. Children start to communicate when they are born. Infants can smile, coo, cry or turn their heads away when they are trying to get your attention to tell you something “Infants begin to categorizing objects as early as 3 or 4 months of age, understand the meaning of some words as early as 8 months of age and typically say their first word at about 12 months” (Byrnes & Wasik, 2009). “By the time children are 16 to 18 months old, many have 50 words in their expressive vocabularies” (Byrnes & Wasik, 2009). As children get older their vocabulary expands tremendously. Preschool aged children are able to organize their words into different groups (i.e. whales, fish, sand are all in the water). You can always scaffold a child’s vocabulary by introducing new words, pictures or other items to increase their language base. Children learn by doing and by modeling behavior.
