Here's my story... My son is 19 months old. He said NO words up until recently. I was very concerned!! My husband, his family, and my family scoffed at me and said "all children talk in their own time and don't worry. He is so advanced in motor skills". Well, of course I still worried (fears of autism, delayed development kept me up at night) Finally at his 18 month appointment, I addressed it with my doctor. She was the only one who supported me to get him evaluated. Well, yesterday we went in for our evaluation and he is 50% behind in receptive communication! No autism, off the charts in fine and gross motor skills, and average in cognitive/academic, and self. He qualifies for a speech pathologist to come to our house weekly for therapy. Because of this EARLY intervention they say within a few months he should be back on track and will have no further development problems later on down the road! I feel so much relief to finally know! And a little justified bc I wasn't crazy for thinking something was off. YOU are your child's advocate! Why not get your son evaluated? It is free through your state. If it is something, the sooner he gets help the better and if it's nothing won't you be glad to have that peace of mind??
