I found that his dis/likes really change from day to day, I guess just like with us. So I just keep offering him the food and he decides wether he wants some or not. If he didn't like one thing for the first time, I keep trying or vary the way I process it. At least now he is eating more veggies again, there was a time where he only wanted carbs like pasta, bread, and I guess potatoes. Silly guy...
