Its frustrating, ive been there so i know how it feels. Have u tried mashed sweet potatoes with boiled titus fish? fruits puree will also help stimulate his appetite then try and be patient with him. Let him feed himself, thats another magic that worked for me. Get a clean nylon like mackintosh, put him on d nylon and place d food before him e.g, rice or noodles, just be there to monitor, he will play with d food and eat some, wash d nylon and keep in a clean place. Then add little or no pepper to his food. All d best!
