Why are you even pandering to this? Someone has really started something here! I have never in all of my 56 years heard anything so weird. You make it sound like it is a phase every child goes through! Trust me, it is not and I would put a stop to it as soon as possible. By not doing so, you are setting the child up for BIG problems when he gets older. You are endorsing the behaviour as being normal, for a child of any age, that is not. If you want the child to have a very strange relationship with food for the rest of its life, carry on!
