Language Development Birth-2 Years Old

Explanation
Babies start recognizing their mother's voice at a very early age, typically less than a month old. This is because they have been hearing their mother's voice while in the womb, and it becomes familiar to them. The sound of their mother's voice provides comfort and security to the baby, and they can distinguish it from other voices. This early recognition of their mother's voice is an important bonding experience between the mother and the child.

Explanation
The given options describe various developmental milestones related to language skills. Startling at loud noises, following objects with eyes, and locating sounds and voices are all behaviors that indicate a baby's ability to perceive and respond to auditory stimuli, which is an important aspect of language development. On the other hand, waving hello/goodbye is a social gesture rather than a language skill, and therefore it is not directly related to language development.

Explanation
Between 7-9 months, a child starts comprehending the word "no". At this age, babies begin to understand simple commands and can recognize the tone of voice used when saying "no". They may not always follow the instruction, but they are able to comprehend the meaning behind the word. This is an important milestone in their cognitive development as they start to understand boundaries and learn to respond to verbal cues.

Explanation
Animal noises are expected to develop at the age of 7-9 months. This is because during this stage of development, infants begin to explore and imitate sounds they hear in their environment. They start to experiment with making different sounds, including animal noises. By this age, they have developed enough control over their vocal cords and mouth muscles to produce these sounds. Additionally, they have also started to understand cause and effect relationships, which allows them to associate certain sounds with specific animals.

Explanation
A child typically starts putting together two or more word sentences between the ages of 19-24 months. During this time, their language skills and vocabulary have developed enough for them to combine words and form simple sentences. This stage is known as the telegraphic stage, where children use mainly content words and omit function words. They are able to express their needs, wants, and ideas more effectively through these sentences.

Explanation
Children start connecting words with objects between the ages of 7-12 months. During this time, they begin to understand that certain words are associated with specific objects or actions. They may start to point at objects when they hear the corresponding word or show recognition when certain words are mentioned. This is an important milestone in language development as it shows that children are beginning to make connections between spoken words and the world around them.

Explanation
Children can start to follow simple commands between the ages of 1-2 years old. During this stage of development, children have acquired the necessary cognitive and language skills to understand and respond to basic instructions. They are able to comprehend and carry out simple tasks or requests given to them by adults or caregivers. This ability to follow commands is an important milestone in a child's development as it signifies their growing understanding and communication skills.

Explanation
A child comprehends the word "no" at around 7-9 months. At this age, babies start to understand simple words and commands. They may not fully grasp the meaning of "no" but they begin to recognize it as a word that is often used by their caregivers to indicate something is not allowed. This is an important milestone in their cognitive development as they start to understand and respond to simple instructions and boundaries.

Explanation
Babbling actually begins around 6 to 9 months old, not after 12 months. This is when infants start making repetitive syllables like "ba-ba" or "da-da" as they experiment with their vocal cords and learn to produce sounds. It is an important milestone in language development and typically precedes the emergence of meaningful words.

Explanation
At 11 months, children are typically in the early stages of language development and are just starting to understand and produce words. They may be able to say a few simple words or imitate sounds, but they are not yet able to put words together to form sentences. This milestone typically occurs around 18-24 months of age when children enter the two-word stage of language development. Therefore, the statement that children start to put words together to form sentences at 11 months is false.

Explanation
Babies typically start smiling in response to familiar voices around the age of birth to 12 months. This is an important developmental milestone as it indicates the baby's ability to recognize and respond to familiar people and sounds. Smiling in response to familiar voices is a social behavior that helps strengthen the bond between the baby and their caregivers.

Explanation
Playing music can indeed help with language development in a child. Studies have shown that exposure to music can enhance a child's ability to learn and understand language. Music engages various areas of the brain, including those involved in language processing, memory, and attention. It can improve vocabulary, pronunciation, and comprehension skills. Additionally, music often incorporates rhythm and rhyme, which can aid in the development of phonological awareness, an essential skill for reading and language acquisition. Therefore, playing music is a beneficial activity for promoting language development in children.

Explanation
A child first reacts to sounds at the age group of 4-6 months. This is when their auditory system has developed enough for them to start responding to sounds in their environment. Before this age, their hearing is still developing, and they may not show significant reactions to sounds. As they reach 4-6 months, they become more aware of their surroundings and start to turn their heads towards sounds, showing that they are able to hear and respond to auditory stimuli.

Explanation
Reading colorful books and pointing to and reading the pictures is a good way to help develop language in a child. Colorful books and pictures can capture a child's attention and stimulate their imagination, making the reading experience more engaging. Pointing to and reading the pictures can also encourage the child to associate words with visual representations, helping them to develop their vocabulary and language skills. Therefore, the statement that it is not a good way to help develop language in a child is false.

Explanation
Babies do not automatically know their names at birth, but they can start recognizing and responding to their names as early as a few months old. By the age of 6 months, many babies are able to recognize their own names and turn their attention towards the sound when called. Therefore, the statement that a baby doesn't know its name until it's at least 6 months old is false.
