Hi Tracy,
Please do not worry, your 4yr old is just showing some control and it is wise not to 'push' or force the issue. He will eat what and when he needs and they may not be when we want them to! I run ToddlerCalm workshops and we have an eating session, you are welcome to contact me I may be able to give you some more info that may help you move this forward, too much to post here. email me
