Is my child speech or language delayed?
Both social and academic success depend on well developed speech and language skills. Your child may be having difficulty developing these skills if:
1. Your child has experienced ear infections or an unusually long stay in the hospital.
2. Your child is not understood by playmates or others outside the immediate family.
3. Your child gets frustrated when trying to communicate and the situation does not improve over a one- or two-month period.
4. There is a delay of one year or more in developing speech and language skills. For example, here is a sample of abnormal language development (compiled by Beth Witt):
Three year old:
~Says only one or two words at a time.
~Cannot answer "what" or "who" questions
~Speech is not comprehensible except in known context
~Doesn not seem to hear or understand all that is said; seems to "tune out" what others say
~ Does not start conversations. Speaks only when spoken to
~Does not understand spoken directions without visual assistance from pointing and other gestures.
~Repeats what others say instead of responding.
Four year old:
~Talks in only two- or three word phrases. Word order is poor.
~Cannot answer simple "what, where, or why" questions.
~Sentences or words are jumbled and disordered-hard to understand
~Does not talk to adults or peers unless prodded, and then talks as little as possible
~Does not respond to simple two step directions: "Go to the kitchen. Bring me a spoon."
~Cannot listen to two or three lines of a story and answer simple questions about what was read.
