Your child’s speech intelligibility


This chart provides information regarding your little one’s clarity of speech….specifically… how well should your little one’s speech be at 18 months of age…at two years of age…at three years of age…and at four years of age.  I find it to be a helpful resource for parents….especially when I am evaluating a little one under three years of age….at that age I am concerned with quantity NOT clarity.  What does that mean?  It means that I want a little one…three years and under to have words in their vocabulary….I want them to understand that words have meaning…and that words work to get them what they want…..after three years of age I will look more closely at a little one’s clarity of speech (articulation)….and at three years of age…and even at four..and five…your little one does not have to clearly produce all of the sounds in the English language…the TH sound in bathtub is one of the more challenging sounds….we give children up until seven years of age to master this sound!

My name is Kim Marino and I have been practicing as a licensed speech and language pathologist since 1993. I work on Long Island providing diagnostic evaluations and services to children from birth to age 21. My experience is vast and am proud to say that I work with children that may present with articulation and phonological concerns, oral motor feeding concerns, Down Syndrome feeding, cognitive rehabilitation, auditory processing delays, receptive language delays, cleft palate feeding and sound development and expressive language delays. Most importantly, I am the mother of four amazing children and am happily married to my childhood sweetheart. I feel blessed to have my four children and so lucky to share this journey in life with my husband. I always had it somewhere in my head that I wanted to develop a blog or a website of some sort so that I could provide families with an additional that parents could help their little ones become a better communicator. And as I was developing this blog....I realized that I also needed to share the stories about my life and my children....and the funny things along the way that help to keep me smiling. Whether you are a working mother or not...finding balance between home, children and life can be a challenge....I hope that my blog helps to bring a smile to your face..and also some tools to help you help your little or big one. I hope you enjoy! Kim
