“When should my child be speaking in full sentences?” “Is this common for his/her age?” "Should I be able to understand most of what my child says at this age?" - These are common questions speech therapists receive from concerned parents of young children. While we know that all children develop differently and at different paces, there are specific guidelines to help parents monitor their child's development. 

The following is a list of clinical clues that are cause of concern in a child's development of speech and language in various age groups.
A referral to a speech language pathologist is recommended if a parent observes any of these causes of concern:

  • lack of consistent patterns of reduplicative babbling
  • lack of responses indicating comprehension of words or communicative gestures

+ At 18 months old:

  • lack of communicative gestures
