Need some advice

My little boy is 20 months old, he’s always sat fine and ate his meals but now it’s a different story. The last few days he has been screaming and having a full blown tantrum to the point where he’s sweating and screaming. Il put the food in his mouth and he spits it out. He eats chips (fries) ok and likes cucumber and tomato but anything else the last two days he’s refusing it. Regarding things that require a spoon I have been feeding him which I’m guessing might be a mistake so please no judgement as we are all learning, but it was purely because I wanted to make sure he was getting enough food and not just playing with it. It’s really effecting me these last couple of days I would love some tips please. I don’t want to see him upset but I’m also running out of patience. Thank you
