Anyone else dealing with this?

St

So my son has started stuffing his face with everything I put on his trays for meals. He's not chewing it and just shoving it in his mouth like hes starving (which he definently isn't). I used to be able to give him larger peices of things and he would hold it and bite and chew slowly until it was finished. Now if I give him something big he tries to put the entire thing in his mouth and of course ends up gagging. So I started giving him smaller peices and he will pick them up one after the other and put them all in his mouth if he can and not chew. I literally have to give him 2 small peices of something at a time now so he actually eats it. I tell him one at time and don't let him put anything else in his mouth and he starts screaming because I'm not letting him eat. This happened overnight. Anyone else?
