My one year old throws food from his high chair. I know a lot of this is to see what happens, but he's been doing it for months so surely he knows by now that it hits the ground?! I say 'no we don't throw food' firmly each time but then he does it again. He watches me as if looking for my reaction most of the times he does this. I try to distract him with another piece of food but it doesn't seem to work. Sometimes I think it's because he's had enough food, but other times he drops the first piece of food he touches and I know he must be at least a bit hungry. Any advice? I don't mind the mess that much, but I do want to ensure that he gets the appropriate level of discipline by age... And as a ftm I'm just not sure when that really starts. I'm a secondary school teacher - give me a surly teenager to deal with any day and I know what to do, but I have no idea what I'm doing with a baby!
