any evidence of teething because food and milk intake can drop substantially if they are in discomfort. If you suspect teething you could try meds 20 mins before a meal to see if it helps. Or relax about the food and medicate before sleep if you need the meds for then. Usually they eat the fridge clean once the bout of teething has passed.
Otherwise, I would just load the spoon and put it down on his tray and provide finger foods. At 10.5 months you really need to move towards family meals and solid food rather than puree or mashed. Even yoghurt can be eaten with fingers and by the handful and he may enjoy the experience, or he may accept the spoon if you load and let him take it. Don't forget 6 weeks from now solids becomes the primary food, it is not too early to give him family meals right now. he might have more interest to be eating what he sees everyone else eating rather than something different.
