[Total: 0    Average: 0/5]

With each passing day and month, you come across new milestones that your baby crosses and you feel joy and pride to see your little one growing. Among all the milestones like sitting, crawling, walking etc, the most exciting one is speech and language. The early words of your baby like dada and baba will gradually become more clear and he will begin to put faces to the names. This will be followed by need based words like water, food or potty. Next will come the common words which you have introduced to him like dog, fan, nose etc. All these inputs help in language development in toddlers. Your child’s words begin by the age of one and by the time they are 4 years old, they have a vocabulary of almost 1500 words and an ability to recite a story.

This is the normal course of development in children but if a child has a hearing trouble in the form of a partial or complete hearing loss, then he will not be able to pick up words or say them. This is simply because he cannot hear them and hence cannot repeat. Family members and parents should interact with the baby since a young age and encourage conversations. By doing so you will be able to identify a problem if there is before the child turns one. Dealing with hearing impairment is all about early intervention and creating a supportive environment in the family to help the child cope with the hearing difficulty.

Effects Of Hearing Loss

Hearing and sense of sound is very crucial for the development of the child in terms of language development, learning and communication skills. An abnormal hearing that is partial or complete hearing loss can have serious implications and earlier the hearing loss occurs in a child, more serious are the implications. Hearing loss affects children in the following ways:

  • There is a clear delay in the receptive and communicative skills as they do not hear your commands and hence cannot perceive or judge what you are saying unless it is said with actions. Similarly they cannot communicate their needs.
  • There are language problems as they do not pick up the basics of a language and hence face difficulties later on in school
  • Communication troubles make these children prone to social pressures.
  • This deficit may affect what they do later on in life for a profession

How To Identify A Speech Delay?

Speech means the use of words by your baby. Speech development age 2 is achieving a vast vocabulary of words. Language is basically putting these words into fixed formats and understanding the meaning of what is said.

The delay in speech and language can be both receptive and expressive. Receptive delay means the child cannot understand what is being said or read to him and expressive delays mean that the child cannot put the words together in a proper sentence even when he understands the meaning.

The following are some red flags to understand speech delay:

  • Your baby doesn’t babble by 9 months
  • The baby has not spoken his first word by 15 months
  • No combination of words by 24 months
  • Slow speech and grasping when spoken too
  • Failure or very slow to respond to commands.
  • No response at all to loud sounds. If there is a hearing impairment in children, this symptom becomes prominent.
  • Not interested in communicating actively
  • If strangers cannot understand what the child says by 36 months of age.

The above may be associated with accessory symptoms like drooling, stammering, difficult coordination of the tongue and face muscles, flustered or stuttered behavior in front of strangers. The presence of symptoms will vary from one child to the other but they are important as they help to pin point where the trouble is.

Therapy For Hearing Problems in Children

It is well understood by now that a child with hearing difficulties will tend to be a little slow and catch up much later than his peers. If you suspect a hearing problem in your child, you should visit an audiologist who will conduct a hearing test to assess the type of hearing loss. However, early identification of the hearing loss can prove to be of immense help as the intervention can be started. The lag in learning in children tends to increase with growing age. If the hearing problem is identified within the first 6 months of life, then early intervention can benefit the child and help him grow normally. This is basically training the child to hear normally again inspite of an impairment. So the entire process is termed as habilitaiton. The methods used in hearing habilitation are:

  1. Listening strategies
  2. Hearing aids are small devices that fit into the ear. They amplify the sound and transmit it to the ear canal. Baby hearing aid are also available but they need to be chosen based on the type of the hearing loss after consultation with an audiologist.
  3. Communication techniques
  4. Use of standardized hand gestures
  5. Use of assitive technology like personal frequency modulation, FM systems, infrared systems and amplified telephones.
  6. Cochlear implants are gaining popularity these days. They are devices that are inserted withing the ear. There is a microphone that is attached to capture the sound and transmit it to the auditory nerve which aids hearing.
