Gabby he's 5 mths old, but maybe move the tray to where he is/was dumping,and also when you clean out his tray try leaving a tiny amount of dump or wee-as i've found especially with boys that they don't like their tray being ultra clean-see not just human lads-me thinks He is at an age where his hormones are kicking in and this could be a way of him asserting his self-so you just have to show him..yes you rule but rule here
