Sometimes there is a reason that a child has a speech and language problem. For instance, a child may have a language delay because of trouble hearing or because of a developmental disorder such as autism. Often, there is not a clear cause.
It's important to track your child's speech and language development. A child can overcome many speech and language problems with treatment, especially when you catch problems early.
Infants start learning in the womb, where they hear and respond to familiar voices. The fastest learning occurs from ages 2 to 5 years.
Speech and language milestones help tell whether a child is developing as expected. Milestones are certain skills, such as babbling, saying "mama" or "dada," or putting two words together. Usually, a child needs to master one milestone before reaching the next.
Babies usually start cooing at around 2 months and are babbling by about 6 months. A child usually speaks in gibberish, called jargon, by the first birthday. At 15 to 18 months, a typical toddler understands much more than he or she is able to put into words. Starting around 18 months, many children have a burst in talking. By 24 months, children tend to use at least 50 words and are also starting to use two-word phrases.
Keep in mind that the age at which children reach milestones varies from child to child. Some children, especially girls, are advanced. Others develop more slowly.
