I thought I digger plate would help he's not too bad with his plate. I have got a coaster for his cup that's on the coffee table. That seems to have worked as he just used to throw it on the floorDoes he throw the plate or just the food? Tbh he will stop it as he gets older. My 18 month old used to always throw her plate, so I stopped giving her one then in the end I just got a suction plate. X
