Ds just 4 does this. It's a continual battle. He plays with food, shouts, calls us silly names squirms around etc. Doesn't do this the rest of the time (too much).
We've tried various tactics. Ignoring, bringing him down from the table, praising good eating not making a big deal of it, etc.
What should we do? Today I felt really harsh because he squirted water out of his mouth, so I immediately took him down and said that he obviously wasn't hungry as he was messing about.
In some ways I feel this was justified, but then I think that he's still really little and question whether I'm doing the right thing. I don't expect him to eat like he's at the queens table or anything, but I do feel like he knows not to do things like his water trick.
Any advice?
