Your child may have an underlying problem in communication if he or she...
Began talking later than expected
Is harder to understand than other kids their age
Is performing below expectations in the classroom
Is having difficulty learning to read
Cannot seem to express his/her thoughts and ideas, uses lots of "filler words" such as "stuff" and "things". Also may be very vague or unclear when explaining something.
Has problems understanding others and following directions
Doesn't pick up on social cues
Has problems taking tests
Says "huh" a lot and needs things repeated often
Does not respond consistently to sounds
If any or some of these ring true for you, and your motherly instinct is telling you something is off, go get your child evaluated. It will put your mind at ease to know what professionals think. If there is a problem, then you can start taking care of it with support from others.
