I am a doctor in the Philippines. I have 3 y/o son who had a Seizure Disorder when he was 6months old which eventually resolved when he was 2 y/o. He also has Global Developmental Delay and has Sensory Integration Dysfunction and Oral Aversion is a major problem. He only drinks milk mixed with infant cereal using his baby bottle and would not take anything else in his mouth. He has been undergoing Occupational And Physical Therapy since 5months old but with very little improvement in feeding. HIs motor and speech is catching up but feeding is still a big problem. We have tried desensitization and we were able to feed him pureed cereals and fruits when he was younger but now that he is much stronger and has more purposeful movements, he is able to move his head away from the spoon, brush our hands aside and even thow away the spoon and bowl when we attempt to feed him by mouth.What can you suggest?
