Maybe look at adding more solids food to meals to. Your lunch for example is just veggies and yogurt or fruit which for me would be the side and dessert. I'd offer a substantial protein like meat, fish, cheese, houmous or egg here too as well as a complex carbohydrate such as bread, pasta, rice, potato or cous cous. And id add some kind of carbs to the dinner as well to really fill him up. f LO is willing to eat it and seems hungry I'd be moving towards offering 3 full and balanced meals like you would eat yourself. I think at 10 months he is probably ready to move past the stage of one or two foods at each sitting.
