Child Language Development: Ages 2-3

Explanation
Two-year-olds can use the words "I" and "you" correctly because at this age they begin to develop a sense of self and can understand the concept of addressing someone else. They may still make grammatical errors or struggle with pronouns, but they can typically use these two words to refer to themselves and others.

Explanation
For two-year-olds, their volume and pitch of voice are not yet well controlled. This means that they may not be able to regulate the loudness or the highness/lowness of their voice effectively. This lack of control can lead to their voice being too loud or too soft, or their pitch being too high or too low. It is important for adults to provide guidance and help children develop these skills as they grow.

Explanation
The correct answer is "My and mine". At around two years old, children begin to develop a sense of ownership and possessiveness. They start to understand the concept of "mine" and "my" in relation to their belongings and personal possessions. This is a normal part of their language development and demonstrates their growing sense of self and individuality.

Explanation
The book "Brown Bear, Bear Bear What Do You See?" is recommended for children ages 2 to 3 in the brochure.

Explanation
The correct answer is 90%. This suggests that approximately 90% of a three-year-old's speech is intelligible, meaning that it can be understood by others. This indicates that at this age, children have developed enough speech and language skills to communicate effectively with others, although there may still be some instances where their speech is unclear or difficult to understand.

Explanation
At three years old, children start to develop their language skills and begin to use more verbs in their speech. Verbs are action words that express what someone or something is doing. This is an important stage in language development as it allows children to communicate their actions and interact with others more effectively. Nouns, adjectives, and conjunctions are also important parts of speech, but at this stage, verbs tend to be more predominant.

Explanation
A two-year-old typically has a vocabulary of 150-300 words. At this age, children are rapidly learning and acquiring new words every day. They are able to understand and use simple words to communicate their needs and desires. While the exact number may vary from child to child, this range is a general estimate of the vocabulary size for a two-year-old.

Explanation
At three years old, children are typically able to speak in short sentences consisting of three words. This is because their language skills are still developing, and they may have a limited vocabulary at this age. While they may be able to understand and use more words individually, constructing longer sentences can be challenging for them. Therefore, the correct answer is 3 words.

Explanation
Using picture books to explore vocabulary, limiting TV time, and singing a song with their child are all effective strategies to increase language development in 2 and 3 year olds. Picture books help children learn new words and expand their vocabulary. Limiting TV time ensures that children have more opportunities for interactive language experiences. Singing songs with a child helps develop their language skills through rhythm, repetition, and exposure to new words. Therefore, all of the above options are recommended for parents to enhance language development in young children.

Explanation
By age 3, children start to develop language skills and engage in various activities that promote language development. Rhyming helps children recognize and manipulate sounds, enhancing their phonological awareness. Singing exposes children to rhythm, melody, and vocabulary, supporting their language acquisition. Listening to stories exposes children to new words, expands their vocabulary, and helps develop comprehension skills. Therefore, all of the mentioned activities contribute to children's language development by age 3.

Explanation
Between the ages of 2 and 3, children typically have utterances that are 1-3 words long. This is because at this stage of language development, children are still learning how to form sentences and express themselves. They often use short phrases or single words to communicate their needs and desires. As they continue to develop their language skills, their utterances will gradually become longer and more complex.

Explanation
During the ages of 2-3, children typically experience a significant growth spurt. This is a period of rapid physical development characterized by an increase in height and weight. It is during this time that children may appear to grow taller and gain weight at a faster rate compared to other stages of their development. This growth spurt is crucial for the child's overall growth and development, as it helps them to reach important milestones and develop their motor skills.

Explanation
Children typically start to get pronouns such as "you" and "me" mixed up around the age of 2. This is because they are still developing their language skills and may not fully understand the concept of pronouns and their proper usage. As they continue to grow and learn, they will eventually grasp the correct usage of pronouns.

Explanation
By three years old, children typically know three prepositions. At this age, children have developed a basic understanding of spatial relationships and can use prepositions like "in," "on," and "under" to describe the position of objects. They may also begin to grasp more complex prepositions such as "behind" or "next to." This knowledge of prepositions is an important milestone in language development and allows children to communicate about location and direction.

Explanation
Between ages 2 and 3, children are starting to engage in a question-answer format. During this developmental stage, children's language skills are rapidly progressing, and they begin to understand the concept of asking and answering questions. They may ask simple questions to seek information or clarification, and they also start responding to questions asked by others. This marks an important milestone in their cognitive and linguistic development, as they learn to communicate and interact with others through questioning and answering.
