I gave him utensils, buys me time to eat as well. He becomes super busy with stabling the food with a fork that once he has it on the fork it goes in his mouth quickly for fear that it’ll fall off
When my son first tried to throw his food, I would pick up the thrown food and react as little as possible (didn't comment on it; did not make any cutesy reactions like "uh oh spaghetti-o" and would just let him continue trying to eat. At this stage, they curious to see food drop to the floor, to learn what happens to the food. Eventually he learned thrown food gets eaten by the dogs and no reaction from mama. He doesn't throw food much anymore - maybe once if it is a new food he is trying.
My daughter used to do it a lot but she kinda has grown out of it. I would tell her “no ma’am” & kinda get onto her for it & eventually she learned not to. Now every once in a while she’ll discard a piece of food. I think it’s normal especially cause their little brains move so fast they don’t really know what they’re doing. At least in my daughter’s case. Sometimes she just drops it and then realizes “oh crap I dropped it I still wanted that”
It’s like an impulse control thing
My boy does this so I just look at how I can arrange the environment to minimize throwing. I will usually put only one or two bites of things at a time on the plate. Then add more if he’s actually eating. If he still throws, then I help put food in his mouth and then see if he’ll do it on his own the next time. If he throws the plate or bowl, then I hold them down. If he throws his drink, I hold it. Some people designate an “all done bowl” where you teach them to put food in the bowl instead of throwing. I haven’t tried that yet myself bc I’ve had success with just limiting opportunities to throw in the first place.
