My daughter would not get near table foods (except Cheerios) at 15 months. I had her evaluated and learned that she had other sensory issues too which I didn't think of as so unusual, but collectively with her feeding/textures issues...amounted to a minor case of Sensory Processing Disorder (SPD). She is getting Occupational Therapy, and her eating has come a long way in 4+ months of therapy at the NYU Swallowing Disorders Center. Now at 22 months she still prefers to be fed (because she doesn't like the feeling of food on her fingers), but she will use a fork for a few bites if she is really hungry and we are too busy to feed her at that moment. It's still a process to get her fully on table foods at every meal and to completely self-feed, but she has made great progress since I sought out professional help. By the way, the dry/crunchy texture (like Cheerios and baby/toddler puffs) is often the easiest "table food" texture to accept for children with sensory issues...so keep offering Cheerios several times a day to practice with chewing skills and self-feeding. I am so happy that I did not wait to see if she would "outgrow" the problem, because I have heard of 5-year olds still eating baby food puree. Plus, I didn't want her lack of chewing to affect her oral muscles for speech development. Talk to your pediatrician about getting your son evaluated for his sensory sensitivities.
