Based on the milestones set for typical toddlers, if the child tends to have a lot of or very long delays, they may be deemed as having language delay. However, proper testing by a professional like a speech therapist or a doctors confirmation will be required to determine if a child has language delay. Although these milestones are the typical milestones for a child, they should not be followed strictly as they are mere guidelines. Language development in language delay
Early developmental language delay is characterized by slow language development in preschoolers. Language development for children with language delay takes longer than the general timeline provided above. It is not only slower, but also presents itself in different forms. For example, a child with a language delay could have weaker language skills such as the ability to produce phrases at 24 months-old. They may find themselves producing language that is different from language norms in developing children. Types of Language Delay
A language delay is commonly divided into receptive and expressive categories. Both categories are essential in developing effective communication. Receptive language refers to the process of understanding language, both verbal (spoken) and nonverbal (written, gestural). This may involve gaining information from sounds and words, visual information from surrounding environment, written information and grammar.Expressive language refers to the use of sentences (made of words or signs) to communicate messages to others. It enables children to express their needs and wants to the people around them, interact with others and develop their language skills in speech and writing.
For affected girls who wish (or whose parents wish) to have their hymens preserved, surgical techniques to excise of a central flange of the hymen can be used. The timing of surgical hymen repair is controversial: some doctors believe it is best to intervene immediately after the neonatal period, while others believe that surgical repair should be delayed until puberty, when estrogenization is complete. Epidemiology
Imperforate hymen is the most common vaginal obstruction of congenital origin. Estimates of the frequency of imperforate hymen vary from 1 in 1000 to 1 in 10,000 females. References
